Starting ds9 from loginuser.clStarted by:FSBoyden, 08/21/2006 03:05PM
Hi All

It may sound a stupid Q, but how would
you call DS9 from the loginuser.cl. I
would like to skip the step where I have
to start DS9, and run it in the bg,
before every IRAF session. I am not that
familiar with coding in c-shell.

Thanx
