c
csh(1) csh(1)
breaksw
Causes a break from a switch, resuming after the endsw.
case label:
A label in a switch statement as discussed below.
cd
cd
directory_name
chdir
chdir
directory_name
Change the shell’s current working directory to directory_name. If not specified,
directory_name defaults to your home directory.
If directory_name is not found as a subdirectory of the current working directory (and does
not begin with /, ./,or../), each component of the variable cdpath is checked to see if it
has a subdirectory directory_name. Finally, if all else fails, csh treats directory_name as a
shell variable. If its value begins with /, this is tried to see if it is a directory. See also cd(1).
continue
Continue execution of the nearest enclosing while or foreach. The rest of the commands
on the current line are executed.
default:
Labels the default case in a switch statement. The default should come after all other
case labels.
dirs Prints the directory stack; the top of the stack is at the left; the first directory in the stack is
the current directory.
echo wordlist
echo -n wordlist
The specified words are written to the shell’s standard output, separated by spaces, and ter-
minated with a new-line unless the -n option is specified. See also echo(1).
else
end
endif
endsw
See the descriptions of the foreach, if, switch, and while statements below.
eval arguments ...
(Same behavior as sh(1).) arguments are read as input to the shell and the resulting
command(s) executed. This is usually used to execute commands generated as the result of
command or variable substitution, since parsing occurs before these substitutions.
exec command
The specified command is executed in place of the current shell.
exit
exit (
expression)
csh
exits either with the value of the status variable (first form) or with the value of the
specified expression (second form).
fg [%job ...]
Brings the current (job not specified) or specified jobs into the foreground, continuing them if
they were stopped.
foreach name (wordlist)
...
end
The variable name is successively set to each member of wordlist and the sequence of com-
mands between this command and the matching end are executed. (Both foreach and
end must appear alone on separate lines.)
The built-in command continue can be used to continue the loop prematurely; the built-in
command break to terminate it prematurely. When this command is read from the termi-
nal, the loop is read once, prompting with ? before any statements in the loop are executed.
If you make a mistake while typing in a loop at the terminal, use the erase or line-kill charac-
ter as appropriate to recover.
glob wordlist
Like echo but no \ escapes are recognized and words are delimited by null characters in
