You must be using a csh-derivative.  It is a built-in for the Bourne-
shell family of shells.

Now that you bring it up, I'm not sure how you get this functionality
from a csh environment - I guess just create a script that is just
#/bin/sh

ulimit $*

or something like that...

Did you try doing a "man ulimit"?  It should give the builtin command
support matrix...
