Subject: Need csh alias to match patterns in history

A friend of mine wants a csh alias that will print all lines in
the history list that match a pattern if one is supplied, otherwise
just print the history.

He asked me and I suggested the following csh alias:

alias h ' \
if ( "X\!*" == "X" ) then \
history \
else \
history | grep \!* \
endif'

For some reason, this does not work. Can some kind soul explain why
and supply a working answer to this problem ?

Thanks.
