ok - I'm headed in the right direction. Since I only have one file to
deal with, I can forego the loop operation. I see that I can use
grep and cut to pull the expiration date/time from the file, and use
the date command to get something from the operating system to compare
it to. The only problem now is that the date/time in the file are GMT,
and the server is set to local time (CSTCDT). It's not my machine so I
can't change it.
How can I convert from GMT to local (or vice versa) once I have a
date/time sitting in a variable? Or do I need to do it before hand?
Or what? (clues appreciated)
