unlimit built-in command for tcsh: Remove resource limitations<br />

Format<br />

unlimit [-h] [resource]<br />

Description<br />

unlimit removes the limitation on resource or, if no resource is specified, all<br />

resource limitations.<br />

The hard limit may be lowered to any value that is greater than or equal to the soft<br />

limit. All hard limits can be raised only by a process which has superuser authority.<br />

This behavior is identical to ulimit in the z/<strong>OS</strong> shell. If a user attempts to remove<br />

the soft limit on a resource, and their effective UID is not 0, then unlimit will set the<br />

soft limit to the current hard limit value.<br />

Options<br />

–h Corresponding hard limits are removed. Only the superuser may do this.<br />
