csh.1 (2010 09)

c
csh(1) csh(1)
addresspace Maximum address space in bytes for a process
coredumpsize Size of the largest core dump that is created
cputime Maximum number of CPU seconds to be used by each process
datasize Maximum growth of the data region allowed beyond the end of
the program text
descriptors Maximum number of open files for each process
filesize Largest single file that can be created
memoryuse Maximum size to which a process’s resident set size can grow
stacksize Maximum size of the automatically extended stack region
The maximum_use argument can be specified as a floating-point or integer number followed
by a scale factor: k or kilobytes (1024 bytes), m or megabytes ,orb or blocks (the units used
by the ulimit system call). For both resource names and scale factors, unambiguous
prefixes of the names can be used. filesize can be lowered by an instance of
csh, but can
only be raised by an instance whose effective user ID is root . For more information, refer to
the documentation for the ulimit system call.
login Terminates a login shell, replacing it with an instance of
/usr/bin/login. This is one
way to log off, included for compatibility with sh(1).
logout
Terminates a login shell. Especially useful if ignoreeof is set. A similar function,
bye,
which works for sessions that are not login shells, 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.
newgrp
Changes the group identification of the caller; for details see newgrp (1). A new shell is exe-
cuted by newgrp so that the current shell environment is lost.
nice
nice +number
nice command
nice +number command
The first form sets the nice (run command priority) for this shell to 4 (the default). The
second form sets the priority to the given number. The final two forms run command at
priority 4 and number respectively. The user with appropriate privileges can raise the
priority by specifying negative niceness using
nice -number ... command is always exe-
cuted in a sub-shell, and restrictions placed on commands in simple if statements apply.
See also nice (1).
nohup [ command ]
Without an argument, nohup can be used in shell scripts to cause hangups to be ignored
for the remainder of the script. With an argument, causes the specified command to be run
with hangups ignored. All processes executed in the background with & are effectively
nohuped as described under Jobs in the COMMANDS section.
notify [ job ... ]
Causes the shell to notify the user asynchronously when the status of the current (job not
specified) or specified jobs changes; normally notification is presented before a prompt.
This is automatic if the shell variable notify is set.
onintr [-][label ]
Controls the action of the shell on interrupts. With no arguments, onintr restores the
default action of the shell on interrupts, which action is to terminate shell scripts or return
to the terminal command input level. If - is specified, all interrupts are ignored. If a label
is given, the shell executes a goto label when an interrupt is received or a child process
terminates because it was interrupted.
If the shell is running in the background and interrupts are being ignored, onintr has no
effect; interrupts continue to be ignored by the shell and all invoked commands.
popd [ +n ]
Pops the directory stack, returning to the new top directory. With an argument, discards
