# @(#)README 8.1 (Berkeley) 6/9/93
Notes about the contents of the /etc/kerberosIV directory:
The file master_key contains a copy of the master key under which the
entire Kerberos database is encrypted. Disclosing this key would be bad
news. The reason it is stored in the filesystem is because the following
programs need to inspect or modify the kereros database, and so the key
must be available for them, (or else it would have to be typed in by
hand):
- kerberos (the server itself)
- registerd (for new user registration)
- kpasswdd (for changing passwords)
The srvtab file contains the encryption keys for each service on the local
host. Any host offering network services would have a key here, although
many such files can be used.
The principal.* files comprise the Kerberos database itself, and contain
keys for all principles, and should not be world-readable.
The kerberos.conf file contains the configuration for this machine:
- which realm I'm in
- which servers I should talk to for this realm
The kerberos.realms file contains the name of Kerberos servers for
various (sub)domains.
Kerberos log information it placed in /var/log/kerberos.log
(see rc.local to change it)
The register_keys directory contains a set of files (all of which begin
with "."), each of which contains a des key used for registering new users
with the system. It is used only by the "registerd" program, and only on
a Kerberos server host.

.Sh NAME
.Nm cat
.Nd concatenate and print files
.Sh SYNOPSIS
.Nm cat
.Op Fl benstuv
.Op Fl
.Op Ar
.Sh DESCRIPTION
The
.Nm cat
utility reads files sequentially, writing them to the standard output.
The
.Ar file
operands are processed in command line order.
A single dash represents the standard input.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl b
Implies the
.Fl n
option but doesn't number blank lines.
.It Fl e
Implies the
.Fl v
option, and displays a dollar sign
.Pq Ql \&$
at the end of each line
as well.
.It Fl n
Number the
.Ar output
lines, starting at 1.
.It Fl s
Squeeze multiple adjacent empty lines, causing the output to be
single spaced.
.It Fl t
Implies the
.Fl v
option, and displays tab characters as
.Pq Ql ^I
as well.
.It Fl u
The
.Fl u
option guarantees that the output is unbuffered.
.It Fl v
Displays non-printing characters so they are visible.
Control characters print as
.Ql ^X
for control-X; the delete
character (octal 0177) prints as
.Ql ^?
Non-ascii characters (with the high bit set) are printed as
.Ql M-
(for meta) followed by the character for the low 7 bits.
.El
.Pp
The
.Nm cat
utility exits 0 on success, and >0 if an error occurs.
.Sh BUGS
Because of the shell language mechanism used to perform output
redirection, the command
.Dq Li cat file1 file 2 > file1
will cause the original data in file1 to be destroyed!

.Os
.Sh NAME
.Nm chmod
.Nd change file modes
.Sh SYNOPSIS
.Nm chmod
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Ar mode
.Ar file ...
.Sh DESCRIPTION
The
.Nm chmod
utility modifies the file mode bits of the listed files
as specified by the
.Ar mode
operand.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl H
If the
.Fl R
option is specified, symbolic links on the command line are followed.
(Symbolic links encountered in the tree traversal are not followed.)
.It Fl L
If the
.Fl R
option is specified, all symbolic links are followed.
.It Fl P
If the
.Fl R
option is specified, no symbolic links are followed.
.It Fl R
Change the modes of the file hierarchies rooted in the files
instead of just the files themselves.
.El
.Pp
Symbolic links do not have modes, so unless the
.Fl H
or
.Fl L
option is set,
.Nm chmod
on a symbolic link always succeeds and has no effect.
The
.Fl H ,
.Fl L
and
.Fl P
options are ignored unless the
.Fl R
option is specified.
In addition, these options override each other and the
command's actions are determined by the last one specified.
.Pp
Only the owner of a file or the super-user is permitted to change
the mode of a file.
.Pp
The
.Nm chmod
utility exits 0 on success, and >0 if an error occurs.
.Sh MODES
Modes may be absolute or symbolic.
An absolute mode is an octal number constructed by
.Ar or-ing
the following values:
.Pp
.Bl -tag -width 6n -compact -offset indent
.It Li 4000
set-user-ID-on-execution
.It Li 2000
set-group-ID-on-execution
.It Li 1000
sticky bit, see chmod(2)
.It Li 0400
read by owner
.It Li 0200
write by owner
.It Li 0100
execute (or search for directories) by owner
.It Li 0070
read, write, execute/search by group
.It Li 0007
read, write, execute/search by others
.El
.Pp
The read, write, and execute/search values for group and others
are encoded as described for owner.
.Pp
The symbolic mode is described by the following grammar:
.Bd -literal -offset indent
mode ::= clause [, clause ...]
clause ::= [who ...] [action ...] last_action
action ::= op [perm ...]
last_action ::= op [perm ...]
who ::= a | u | g | o
op ::= + | \- | =
perm ::= r | s | t | w | x | X | u | g | o
.Ed
.Pp
The
.Ar who
symbols ``u'', ``g'', and ``o'' specify the user, group, and other parts
of the mode bits, respectively.
The
.Ar who
symbol ``a'' is equivalent to ``ugo''.
.Pp
.ne 1i
The
.Ar perm
symbols represent the portions of the mode bits as follows:
.Pp
.Bl -tag -width Ds -compact -offset indent
.It r
The read bits.
.It s
The set-user-ID-on-execution and set-group-ID-on-execution bits.
.It t
The sticky bit.
.It w
The write bits.
.It x
The execute/search bits.
.It X
The execute/search bits if the file is a directory or any of the
execute/search bits are set in the original (unmodified) mode.
Operations with the
.Ar perm
symbol ``X'' are only meaningful in conjunction with the
.Ar op
symbol ``+'', and are ignored in all other cases.
.It u
The user permission bits in the mode of the original file.
.It g
The group permission bits in the mode of the original file.
.It o
The other permission bits in the mode of the original file.
.El
.Pp
The
.Ar op
symbols represent the operation performed, as follows:
.Bl -tag -width 4n
.It +
If no value is supplied for
.Ar perm ,
the ``+'' operation has no effect.
If no value is supplied for
.Ar who ,
each permission bit specified in
.Ar perm ,
for which the corresponding bit in the file mode creation mask
is clear, is set.
Otherwise, the mode bits represented by the specified
.Ar who
and
.Ar perm
values are set.
.It \&\-
If no value is supplied for
.Ar perm ,
the ``\-'' operation has no effect.
If no value is supplied for
.Ar who ,
each permission bit specified in
.Ar perm ,
for which the corresponding bit in the file mode creation mask
is clear, is cleared.
Otherwise, the mode bits represented by the specified
.Ar who
and
.Ar perm
values are cleared.
.It =
The mode bits specified by the
.Ar who
value are cleared, or, if no who value is specified, the owner, group
and other mode bits are cleared.
Then, if no value is supplied for
.Ar who ,
each permission bit specified in
.Ar perm ,
for which the corresponding bit in the file mode creation mask
is clear, is set.
Otherwise, the mode bits represented by the specified
.Ar who
and
.Ar perm
values are set.
.El
.Pp
Each
.Ar clause
specifies one or more operations to be performed on the mode
bits, and each operation is applied to the mode bits in the
order specified.
.Pp
Operations upon the other permissions only (specified by the symbol
``o'' by itself), in combination with the
.Ar perm
symbols ``s'' or ``t'', are ignored.
.Sh EXAMPLES
.Bl -tag -width "u=rwx,go=u-w" -compact
.It Li 644
make a file readable by anyone and writable by the owner only.
.Pp
.It Li go-w
deny write permission to group and others.
.Pp
.It Li =rw,+X
set the read and write permissions to the usual defaults, but
retain any execute permissions that are currently set.
.Pp
.It Li +X
make a directory or file searchable/executable by everyone if it is
already searchable/executable by anyone.
.Pp
.It Li 755
.It Li u=rwx,go=rx
.It Li u=rwx,go=u-w
make a file readable/executable by everyone and writable by the owner only.
.Pp
.It Li go=
clear all mode bits for group and others.
.Pp
.It Li g=u-w
set the group bits equal to the user bits, but clear the group write bit.
.El
.Sh BUGS
There's no
.Ar perm
option for the naughty bits.
.Sh SEE ALSO
.Xr install 1 ,
.Xr chmod 2 ,
.Xr stat 2 ,
.Xr umask 2 ,
.Xr fts 3 ,
.Xr setmode 3 ,
.Xr symlink 7 ,
.Xr chown 8
.Sh STANDARDS
The
.Nm chmod
utility is expected to be POSIX 1003.2
compatible with the exception of the
.Ar perm
symbols
.Dq t
and
.Dq X
which are not included in that standard.

.Sh NAME
.Nm cp
.Nd copy files
.Sh SYNOPSIS
.Nm cp
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Op Fl fip
.Ar source_file target_file
.Nm cp
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Op Fl fip
.Ar source_file ... target_directory
.Sh DESCRIPTION
In the first synopsis form, the
.Nm cp
utility copies the contents of the
.Ar source_file
to the
.Ar target_file .
In the second synopsis form,
the contents of each named
.Ar source_file
is copied to the destination
.Ar target_directory .
The names of the files themselves are not changed.
If
.Nm cp
detects an attempt to copy a file to itself, the copy will fail.
.Pp
The following options are available:
.Bl -tag -width flag
.It Fl H
If the
.Fl R
option is specified, symbolic links on the command line are followed.
(Symbolic links encountered in the tree traversal are not followed.)
.It Fl L
If the
.Fl R
option is specified, all symbolic links are followed.
.It Fl P
If the
.Fl R
option is specified, no symbolic links are followed.
.It Fl R
If
.Ar source_file
designates a directory,
.Nm cp
copies the directory and the entire subtree connected at that point.
This option also causes symbolic links to be copied, rather than
indirected through, and for
.Nm cp
to create special files rather than copying them as normal files.
Created directories have the same mode as the corresponding source
directory, unmodified by the process' umask.
.It Fl f
For each existing destination pathname, remove it and
create a new file, without prompting for confirmation
regardless of its permissions.
(The
.Fl i
option is ignored if the
.Fl f
option is specified.)
.It Fl i
Causes
.Nm cp
to write a prompt to the standard error output before copying a file
that would overwrite an existing file.
If the response from the standard input begins with the character
.Sq Li y ,
the file copy is attempted.
.It Fl p
Causes
.Nm cp
to preserve in the copy as many of the modification time, access time,
file flags, file mode, user ID, and group ID as allowed by permissions.
.Pp
If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not altered.
.Pp
If the source file has its set user ID bit on and the user ID cannot
be preserved, the set user ID bit is not preserved
in the copy's permissions.
If the source file has its set group ID bit on and the group ID cannot
be preserved, the set group ID bit is not preserved
in the copy's permissions.
If the source file has both its set user ID and set group ID bits on,
and either the user ID or group ID cannot be preserved, neither
the set user ID or set group ID bits are preserved in the copy's
permissions.
.El
.Pp
For each destination file that already exists, its contents are
overwritten if permissions allow, but its mode, user ID, and group
ID are unchanged.
.Pp
In the second synopsis form,
.Ar target_directory
must exist unless there is only one named
.Ar source_file
which is a directory and the
.Fl R
flag is specified.
.Pp
If the destination file does not exist, the mode of the source file is
used as modified by the file mode creation mask
.Pf ( Ic umask ,
see
.Xr csh 1 ) .
If the source file has its set user ID bit on, that bit is removed
unless both the source file and the destination file are owned by the
same user.
If the source file has its set group ID bit on, that bit is removed
unless both the source file and the destination file are in the same
group and the user is a member of that group.
If both the set user ID and set group ID bits are set, all of the above
conditions must be fulfilled or both bits are removed.
.Pp
Appropriate permissions are required for file creation or overwriting.
.Pp
Symbolic links are always followed unless the
.Fl R
flag is set, in which case symbolic links are not followed, by default.
The
.Fl H
or
.Fl L
flags (in conjunction with the
.Fl R
flag) cause symbolic links to be followed as described above.
The
.Fl H ,
.Fl L
and
.Fl P
options are ignored unless the
.Fl R
option is specified.
In addition, these options override each other and the
command's actions are determined by the last one specified.
.Pp
.Nm Cp
exits 0 on success, >0 if an error occurred.
.Sh COMPATIBILITY
Historic versions of the
.Nm cp
utility had a
.Fl r
option.
This implementation supports that option, however, its use is strongly
discouraged, as it does not correctly copy special files, symbolic links
or fifo's.
.Sh SEE ALSO
.Xr mv 1 ,
.Xr rcp 1 ,
.Xr umask 2 ,
.Xr fts 3 ,
.Xr symlink 7
.Sh HISTORY
The
.Nm cp
command is expected to be
.St -p1003.2
compatible.

* Cp copies source files to target files.
*
* The global PATH_T structure "to" always contains the path to the
* current target file. Since fts(3) does not change directories,
* this path can be either absolute or dot-realative.
*
* The basic algorithm is to initialize "to" and use fts(3) to traverse
* the file hierarchy rooted in the argument list. A trivial case is the
* case of 'cp file1 file2'. The more interesting case is the case of
* 'cp file1 file2 ... fileN dir' where the hierarchy is traversed and the
* path (relative to the root of the traversal) is appended to dir (stored
* in "to") to form the final target path.

Shell control structures and command scripts
.NH 2
Introduction
.PP
It is possible to place commands in files and to cause shells to be
invoked to read and execute commands from these files,
which are called
.I "shell scripts."
We here detail those features of the shell useful to the writers of such
scripts.
.NH 2
Make
.PP
It is important to first note what shell scripts are
.I not
useful for.
There is a program called
.I make
which is very useful for maintaining a group of related files
or performing sets of operations on related files.
For instance a large program consisting of one or more files
can have its dependencies described in a
.I makefile
which contains definitions of the commands used to create these
different files when changes occur.
Definitions of the means for printing listings, cleaning up the directory
in which the files reside, and installing the resultant programs
are easily, and most appropriately placed in this
.I makefile.
This format is superior and preferable to maintaining a group of shell
procedures to maintain these files.
.PP
Similarly when working on a document a
.I makefile
may be created which defines how different versions of the document
are to be created and which options of
.I nroff
or
.I troff
are appropriate.
.NH 2
Invocation and the argv variable
.PP
A
.I csh
command script may be interpreted by saying
.DS
% csh script ...
.DE
where
.I script
is the name of the file containing a group of
.I csh
commands and
`\&...' is replaced by a sequence of arguments.
The shell places these arguments in the variable
.I argv
and then begins to read commands from the script.
These parameters are then available through the same mechanisms
which are used to reference any other shell variables.
.PP
If you make the file
`script'
executable by doing
.DS
chmod 755 script
.DE
and place a shell comment at the beginning of the shell script
(i.e. begin the file with a `#' character)
then a `/bin/csh' will automatically be invoked to execute `script' when
you type
.DS
script
.DE
If the file does not begin with a `#' then the standard shell
`/bin/sh' will be used to execute it.
This allows you to convert your older shell scripts to use
.I csh
at your convenience.
.NH 2
Variable substitution
.PP
After each input line is broken into words and history substitutions
are done on it, the input line is parsed into distinct commands.
Before each command is executed a mechanism know as
.I "variable substitution"
is done on these words.
Keyed by the character `$' this substitution replaces the names
of variables by their values.
Thus
.DS
echo $argv
.DE
when placed in a command script would cause the current value of the
variable
.I argv
to be echoed to the output of the shell script.
It is an error for
.I argv
to be unset at this point.
.PP
A number of notations are provided for accessing components and attributes
of variables.
The notation
.DS
$?name
.DE
expands to `1' if name is
.I set
or to `0'
if name is not
.I set.
It is the fundamental mechanism used for checking whether particular
variables have been assigned values.
All other forms of reference to undefined variables cause errors.
.PP
The notation
.DS
$#name
.DE
expands to the number of elements in the variable
.I name.
Thus
.DS
% set argv=(a b c)
% echo $?argv
1
% echo $#argv
3
% unset argv
% echo $?argv
0
% echo $argv
Undefined variable: argv.
%
.DE
.PP
It is also possible to access the components of a variable
which has several values.
Thus
.DS
$argv[1]
.DE
gives the first component of
.I argv
or in the example above `a'.
Similarly
.DS
$argv[$#argv]
.DE
would give `c',
and
.DS
$argv[1\-2]
.DE
would give `a b'. Other notations useful in shell scripts are
.DS
$\fIn\fR
.DE
where
.I n
is an integer as a shorthand for
.DS
$argv[\fIn\fR\|]
.DE
the
.I n\|th
parameter and
.DS
$*
.DE
which is a shorthand for
.DS
$argv
.DE
The form
.DS
$$
.DE
expands to the process number of the current shell.
Since this process number is unique in the system it can
be used in generation of unique temporary file names.
The form
.DS
$<
.DE
is quite special and is replaced by the next line of input read from
the shell's standard input (not the script it is reading). This is
useful for writing shell scripts that are interactive, reading
commands from the terminal, or even writing a shell script that
acts as a filter, reading lines from its input file. Thus the sequence
.DS
echo 'yes or no?\ec'
set a=($<)
.DE
would write out the prompt `yes or no?' without a newline and then
read the answer into the variable `a'. In this case `$#a' would be
`0' if either a blank line or end-of-file (^D) was typed.
.PP
One minor difference between `$\fIn\fR\|' and `$argv[\fIn\fR\|]'
should be noted here.
The form
`$argv[\fIn\fR\|]'
will yield an error if
.I n
is not in the range
`1\-$#argv'
while `$n'
will never yield an out of range subscript error.
This is for compatibility with the way older shells handled parameters.
.PP
Another important point is that it is never an error to give a subrange
of the form `n\-'; if there are less than
.I n
components of the given variable then no words are substituted.
A range of the form `m\-n' likewise returns an empty vector without giving
an error when \fIm\fR exceeds the number of elements of the given variable,
provided the subscript \fIn\fR is in range.
.NH 2
Expressions
.PP
In order for interesting shell scripts to be constructed it
must be possible to evaluate expressions in the shell based on the
values of variables.
In fact, all the arithmetic operations of the language C are available
in the shell
with the same precedence that they have in C.
In particular, the operations `==' and `!=' compare strings
and the operators `&&' and `|\|\||' implement the boolean and/or operations.
The special operators `=~' and `!~' are similar to `==' and `!=' except
that the string on the right side can have pattern matching characters
(like *, ? or []) and the test is whether the string on the left matches
the pattern on the right.
.PP
The shell also allows file enquiries of the form
.DS
\-? filename
.DE
where `?' is replace by a number of single characters.
For instance the expression primitive
.DS
\-e filename
.DE
tell whether the file
`filename'
exists.
Other primitives test for read, write and execute access to the file,
whether it is a directory, or has non-zero length.
.PP
It is possible to test whether a command terminates normally,
by a primitive of the
form `{ command }' which returns true, i.e. `1' if the command
succeeds exiting normally with exit status 0, or `0' if the command
terminates abnormally or with exit status non-zero.
If more detailed information about the execution status of a command
is required, it can be executed and the variable `$status' examined
in the next command.
Since `$status' is set by every command, it is very transient.
It can be saved if it is inconvenient to use it only in the single
immediately following command.
.PP
For a full list of expression components available see the manual
section for the shell.
.NH 2
Sample shell script
.PP
A sample shell script which makes use of the expression mechanism
of the shell and some of its control structure follows:
.DS
% cat copyc
#
# Copyc copies those C programs in the specified list
# to the directory ~/backup if they differ from the files
# already in ~/backup
#
set noglob
foreach i ($argv)
if ($i !~ *.c) continue # not a .c file so do nothing
if (! \-r ~/backup/$i:t) then
echo $i:t not in backup... not cp\e\'ed
continue
endif
cmp \-s $i ~/backup/$i:t # to set $status
if ($status != 0) then
echo new backup of $i
cp $i ~/backup/$i:t
endif
end
.DE
.PP
This script makes use of the
.I foreach
command, which causes the shell to execute the commands between the
.I foreach
and the matching
.I end
for each of the values given between `(' and `)' with the named
variable, in this case `i' set to successive values in the list.
Within this loop we may use the command
.I break
to stop executing the loop
and
.I continue
to prematurely terminate one iteration
and begin the next.
After the
.I foreach
loop the iteration variable
(\fIi\fR in this case)
has the value at the last iteration.
.PP
We set the variable
.I noglob
here to prevent filename expansion of the members of
.I argv.
This is a good idea, in general, if the arguments to a shell script
are filenames which have already been expanded or if the arguments
may contain filename expansion metacharacters.
It is also possible to quote each use of a `$' variable expansion,
but this is harder and less reliable.
.PP
The other control construct used here is a statement of the form
.DS
\fBif\fR ( expression ) \fBthen\fR
command
...
\fBendif\fR
.DE
The placement of the keywords here is
.B not
flexible due to the current implementation of the shell.\(dg
.FS
\(dgThe following two formats are not currently acceptable to the shell:
.sp
.in +5
.nf
\fBif\fR ( expression ) # \fBWon't work!\fR
\fBthen\fR
command
...
\fBendif\fR
.fi
.in -5
.sp
and
.sp
.in +5
.nf
\fBif\fR ( expression ) \fBthen\fR command \fBendif\fR # \fBWon't work\fR
.in -5
.fi
.FE
.PP
The shell does have another form of the if statement of the form
.DS
\fBif\fR ( expression ) \fBcommand\fR
.DE
which can be written
.DS
\fBif\fR ( expression ) \e
command
.DE
Here we have escaped the newline for the sake of appearance.
The command must not involve `\||\|', `&' or `;'
and must not be another control command.
The second form requires the final `\e' to
.B immediately
precede the end-of-line.
.PP
The more general
.I if
statements above also admit a sequence of
.I else\-if
pairs followed by a single
.I else
and an
.I endif,
e.g.:
.DS
\fBif\fR ( expression ) \fBthen\fR
commands
\fBelse\fR \fBif\fR (expression ) \fBthen\fR
commands
\&...
\fBelse\fR
commands
\fBendif\fR
.DE
.PP
Another important mechanism used in shell scripts is the `:' modifier.
We can use the modifier `:r' here to extract a root of a filename or
`:e' to extract the
.I extension.
Thus if the variable
.I i
has the value
`/mnt/foo.bar'
then
.sp
.in +5
.nf
% echo $i $i:r $i:e
/mnt/foo.bar /mnt/foo bar
%
.sp
.in -5
.fi
shows how the `:r' modifier strips off the trailing `.bar' and the
the `:e' modifier leaves only the `bar'.
Other modifiers will take off the last component of a pathname leaving
the head `:h' or all but the last component of a pathname leaving the
tail `:t'.
These modifiers are fully described in the
.I csh
manual pages in the User's Reference Manual.
It is also possible to use the
.I "command substitution"
mechanism described in the next major section to perform modifications
on strings to then reenter the shell's environment.
Since each usage of this mechanism involves the creation of a new process,
it is much more expensive to use than the `:' modification mechanism.\(dd
.FS
\(dd It is also important to note that
the current implementation of the shell limits the number of `:' modifiers
on a `$' substitution to 1.
Thus
.sp
.nf
.in +5
% echo $i $i:h:t
/a/b/c /a/b:t
%
.in -5
.fi
.sp
does not do what one would expect.
.FE
Finally, we note that the character `#' lexically introduces a shell
comment in shell scripts (but not from the terminal).
All subsequent characters on the input line after a `#' are discarded
by the shell.
This character can be quoted using `\'' or `\e' to place it in
an argument word.
.NH 2
Other control structures
.PP
The shell also has control structures
.I while
and
.I switch
similar to those of C.
These take the forms
.DS
\fBwhile\fR ( expression )
commands
\fBend\fR
.DE
and
.DS
\fBswitch\fR ( word )
\fBcase\fR str1:
commands
\fBbreaksw\fR
\& ...
\fBcase\fR strn:
commands
\fBbreaksw\fR
\fBdefault:\fR
commands
\fBbreaksw\fR
\fBendsw\fR
.DE
For details see the manual section for
.I csh.
C programmers should note that we use
.I breaksw
to exit from a
.I switch
while
.I break
exits a
.I while
or
.I foreach
loop.
A common mistake to make in
.I csh
scripts is to use
.I break
rather than
.I breaksw
in switches.
.PP
Finally,
.I csh
allows a
.I goto
statement, with labels looking like they do in C, i.e.:
.DS
loop:
commands
\fBgoto\fR loop
.DE
.NH 2
Supplying input to commands
.PP
Commands run from shell scripts receive by default the standard
input of the shell which is running the script.
This is different from previous shells running
under \s-2UNIX\s0. It allows shell scripts to fully participate
in pipelines, but mandates extra notation for commands which are to take
inline data.
.PP
Thus we need a metanotation for supplying inline data to commands in
shell scripts.
As an example, consider this script which runs the editor to
delete leading blanks from the lines in each argument file:
.DS
% cat deblank
# deblank \-\- remove leading blanks
foreach i ($argv)
ed \- $i << \'EOF\'
1,$s/^[ ]*//
w
q
\&\'EOF\'
end
%
.DE
The notation `<< \'EOF\''
means that the standard input for the
.I ed
command is to come from the text in the shell script file
up to the next line consisting of exactly `\'EOF\''.
The fact that the `EOF' is enclosed in `\'' characters, i.e. quoted,
causes the shell to not perform variable substitution on the
intervening lines.
In general, if any part of the word following the `<<' which the
shell uses to terminate the text to be given to the command is quoted
then these substitutions will not be performed.
In this case since we used the form `1,$' in our editor script
we needed to insure that this `$' was not variable substituted.
We could also have insured this by preceding the `$' here with a `\e',
i.e.:
.DS
1,\e$s/^[ ]*//
.DE
but quoting the `EOF' terminator is a more reliable way of achieving the
same thing.
.NH 2
Catching interrupts
.PP
If our shell script creates temporary files, we may wish to catch
interruptions of the shell script so that we can clean up
these files.
We can then do
.DS
onintr label
.DE
where
.I label
is a label in our program.
If an interrupt is received the shell will do a
`goto label'
and we can remove the temporary files and then do an
.I exit
command (which is built in to the shell)
to exit from the shell script.
If we wish to exit with a non-zero status we can do
.DS
exit(1)
.DE
e.g. to exit with status `1'.
.NH 2
What else?
.PP
There are other features of the shell useful to writers of shell
procedures.
The
.I verbose
and
.I echo
options and the related
.I \-v
and
.I \-x
command line options can be used to help trace the actions of the shell.
The
.I \-n
option causes the shell only to read commands and not to execute
them and may sometimes be of use.
.PP
One other thing to note is that
.I csh
will not execute shell scripts which do not begin with the
character `#', that is shell scripts that do not begin with a comment.
Similarly, the `/bin/sh' on your system may well defer to `csh'
to interpret shell scripts which begin with `#'.
This allows shell scripts for both shells to live in harmony.
.PP
There is also another quotation mechanism using `"' which allows
only some of the expansion mechanisms we have so far discussed to occur
on the quoted string and serves to make this string into a single word
as `\'' does.

Other, less commonly used, shell features
.NH 2
Loops at the terminal; variables as vectors
.PP
It is occasionally useful to use the
.I foreach
control structure at the terminal to aid in performing a number
of similar commands.
For instance, there were at one point three shells in use on the Cory \s-2UNIX\s0
system at Cory Hall,
`/bin/sh',
`/bin/nsh',
and
`/bin/csh'.
To count the number of persons using each shell one could have issued
the commands
.DS
% grep \-c csh$ /etc/passwd
27
% grep \-c nsh$ /etc/passwd
128
% grep \-c \-v sh$ /etc/passwd
430
%
.DE
Since these commands are very similar we can use
.I foreach
to do this more easily.
.DS
% foreach i (\'sh$\' \'csh$\' \'\-v sh$\')
? grep \-c $i /etc/passwd
? end
27
128
430
%
.DE
Note here that the shell prompts for
input with `? ' when reading the body of the loop.
.PP
Very useful with loops are variables which contain lists of filenames
or other words.
You can, for example, do
.DS
% set a=(\`ls\`)
% echo $a
csh.n csh.rm
% ls
csh.n
csh.rm
% echo $#a
2
%
.DE
The
.I set
command here gave the variable
.I a
a list of all the filenames in the current directory as value.
We can then iterate over these names to perform any chosen function.
.PP
The output of a command within `\`' characters is converted by
the shell to a list of words.
You can also place the `\`' quoted string within `"' characters
to take each (non-empty) line as a component of the variable;
preventing the lines from being split into words at blanks and tabs.
A modifier `:x' exists which can be used later to expand each component
of the variable into another variable splitting it into separate words
at embedded blanks and tabs.
.NH 2
Braces { ... } in argument expansion
.PP
Another form of filename expansion, alluded
to before involves the characters `{' and `}'.
These characters specify that the contained strings, separated by `,'
are to be consecutively substituted into the containing characters
and the results expanded left to right.
Thus
.DS
A{str1,str2,...strn}B
.DE
expands to
.DS
Astr1B Astr2B ... AstrnB
.DE
This expansion occurs before the other filename expansions, and may
be applied recursively (i.e. nested).
The results of each expanded string are sorted separately, left
to right order being preserved.
The resulting filenames are not required to exist if no other expansion
mechanisms are used.
This means that this mechanism can be used to generate arguments which are
not filenames, but which have common parts.
.PP
A typical use of this would be
.DS
mkdir ~/{hdrs,retrofit,csh}
.DE
to make subdirectories `hdrs', `retrofit' and `csh'
in your home directory.
This mechanism is most useful when the common prefix is longer
than in this example, i.e.
.DS
chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}}
.DE
.NH 2
Command substitution
.PP
A command enclosed in `\`' characters is replaced, just before
filenames are expanded, by the output from that command.
Thus it is possible to do
.DS
set pwd=\`pwd\`
.DE
to save the current directory in the variable
.I pwd
or to do
.DS
ex \`grep \-l TRACE *.c\`
.DE
to run the editor
.I ex
supplying as arguments those files whose names end in `.c'
which have the string `TRACE' in them.*
.FS
*Command expansion also occurs in input redirected with `<<'
and within `"' quotations.
Refer to the shell manual section for full details.
.FE
.NH 2
Other details not covered here
.PP
In particular circumstances it may be necessary to know the exact
nature and order of different substitutions performed by the shell.
The exact meaning of certain combinations of quotations is also
occasionally important.
These are detailed fully in its manual section.
.PP
The shell has a number of command line option flags mostly of use
in writing \s-2UNIX\s0 programs,
and debugging shell scripts.
See the csh(1) manual section for a list of these options.
