/bin/sh doesn't appear to have any such command. bash and ksh
both have ulimit:
usage: ulimit [-cmdstf] [new limit]
ulimit is more SysV'ish. ulimit -a displays what appears to
be all the limits, but the values are wrong. RTBM for more
information about ulimit.
Did you try exec'ing csh, setting the limit, and exec'ing your
own shell? The limits appear to be process-based and inheritable.
See also getrlimit(2), ulimit(3).
