csh.1 (2010 09)

c
csh(1) csh(1)
the n th entry in the stack. The elements of the directory stack are numbered from 0 start-
ing at the top. A synonym for
popd, called rd, is provided for historical reasons. Its use is
not recommended because it is not part of the standard BSD
csh and may not be sup-
ported in future releases.
pushd [ name ][+n ]
With no arguments, pushd exchanges the top two elements of the directory stack. Given a
name argument, pushd changes to the new directory (using cd) and pushes the old current
working directory (as in csw) onto the directory stack. With a numeric argument, pushd
rotates the n th argument of the directory stack around to be the top element and changes
to that directory. The members of the directory stack are numbered from the top starting
at 0. A synonym for pushd, called gd, is provided for historical reasons. Its use is not
recommended since it is not part of the standard BSD
csh and may not be supported in
future releases.
rehash
Causes the internal hash table of the contents of the directories in the path variable to be
recomputed. This is needed if new commands are added to directories in the path while
you are logged in. This should only be necessary if you add commands to one of your own
directories or if a systems programmer changes the contents of one of the system direc-
tories.
repeat count command
The specified command (which is subject to the same restrictions as the command in the
one-line if statement above) is executed count times. I/O redirections occur exactly once,
even if count is 0.
set
set name
set name=word
set name[ index ]=word
set name=( wordlist )
The first form of set shows the value of all shell variables. Variables whose value is other
than a single word print as a parenthesized word list. The second form sets name to the
null string. The third form sets name to the single word. The fourth form sets the indexth
component of name to word ; this component must already exist. The final form sets name
to the list of words in wordlist . In all cases the value is command and file-name expanded.
These arguments can be repeated to set multiple values in a single set command. Note,
however, that variable expansion happens for all arguments before any setting occurs.
setenv name value
Sets the value of environment variable name to be value , a single string. The most com-
monly used environment variables, USER, TERM, and PATH, are automatically imported to
and exported from the csh variables user , term , and path ; there is no need to use
setenv for these.
shift [ variable ]
If no argument is given, the members of argv are shifted to the left, discarding argv[1].
An error occurs if argv is not set or has less than two strings assigned to it. When vari-
able is specified, shift performs the same function on the specified variable .
source [-h] name
csh reads commands from name . source commands can be nested, but if nested too
deeply the shell may run out of file descriptors or reach the max stack size (see maxssiz (5)).
An error in a source at any level terminates all nested source commands. Normally,
input during source commands is not placed on the history list. The -h option can be
used to place commands in the history list without being executing them.
stop [ %job ... ]
Stops the current (no argument) or specified jobs executing in the background.
suspend
Causes csh to stop as if it had been sent a suspend signal. Since csh normally ignores
suspend signals, this is the only way to suspend the shell. This command gives an error
message if attempted from a login shell.
