I'm still learning shell programming, and have hit a snag that, so far, I
haven't been able to figure out.
Here's what's happening: I'm writing a menu program that, among other things,
allows a user to select the option of up/downloading files to/from a PC.
Since I also have terminals attached, I want to disallow this option unless
the user is working from a port known to have a pc attached to it.
What I have so far: I'm using Bourne shell on AT&T Sys V 3.0 running on a
Unisys 6000/51 platform. I can get the port id with,
who am i | awk '{ print $2 }'
The question is, how do I get this information into a place where I can
test the value? Is there a simpler way than my use of awk?
posted(and I hope I've gotten the right group for followup) and email
replies both welcomed.
Thanks in advance.
