Hello,

I`m trying to set up my ~/.login file so that is the HOSTTYPE variable is set
to "sun3" AND if the TERM variable is set to "sun" (My quotes, both times)
then it should run the alias "X11".

What I tried is:

	if ( ($HOSTTYPE)=sun3 && ($TERM)=sun ) X11

When .login saw this, it did nothing.  When I typed it in a the tcsh prompt
I got the message "if: Expression syntax."  My obvious question, then, is
what is the syntax of the if test expression in (t)csh?

Thanx for any replies!

	if ($HOSTTYPE == sun3 && $TERM == sun) then
		X11
	endif

  Note that aliases won't work in the one-line if statement format, you
have
to use the multiple-line format.

  This is documented quite extensively in the man page.  RTFM.

Seeing as our mail adresses here don't include the actual machine names,
we are unable to cancel messages.  My (Oh so ****ed obvious) errors have
been pointed out to me; no more mail is required.

With luck I'll remember everything else I forgot about UNIX in the last
few months w/o needing to bother you-all.

"==", not "=".  Parenthesize around the whole expression, too:

   if (($HOSTTYPE == sun3) && ($TERM == sun)) X11

As far as csh is concerned, I would try this:

	if( ("$HOSTTYPE" == "sun3") && ("$TERM" == "sun") ) X11

Note the use of spaces (especially around the "==").

Also, RTFM might be helpful in the future (Reading The Friendly? Manual).

Good luck,

and have a nice day...
