THanks!! zgrep KSFO ~/FG/data/navaids/nav.dat.gz worked great.  returned this:

So my next question would be--  for any given airport i want to fly TO, the 5th column that starts with 10890 are the freqs to plug into Nav 1 for a particular runway.  I understand that the morse code identifieer that starts in the column with ISIA lets you know you're tuned in correctly.  HOw do you 'listen' for the station ident in FG? ALso, would you always plug your departure airport into comm/nav 2 to keep in touch with them?
Thanks again.

Or you can use zgrep, which greps zipped files.

I think that was Melchior.  I use his apt and ils scripts a lot.
 
 
Just one thing though, I wonder why you want to know the comms
 
frequencies?  At this stage there is nothing on them apart from the
 
ATIS.  The nav frequencies all work though.
 
 
Here is a link that may help you in finding out nav frequencies:

and an example for KSFO:
