You seem a bit undecided if the trailing / should appear in your device string or not after getting rid of the file name. The sub (...) is there for exactly that - remove the show.version part, so your cut should be unnecessary. Obviously, the sub doesn't do what it is expected to. I guess that due to the space that you introduced which was not present in my original proposal. Playing around a bit with the regex in sub might bring you to where you want to be. You could also substitute the exact string : sub ("show.version", "", FILENAME).

I'm somewhat surprised of the key that you use in sort...

I definitely don't need the /show.version to appear. It doesn't hurt anything, I just prefer not to see it.

I don't fully understand what's going on in {sub (/[^\/]* .$/, "", FILENAME), so I don't get how to modify it to do what I want.

I used sort -k5 because the boss needed the list sorted by the software version, so we can easily see which devices need upgraded. If there's a way to do that with sub as well, I'd love to learn how to make that happen.

Also, I've moved on to turning this script into a function called cpever. The problem I'm running into is that I need to be able to run it from anywhere, and I now need to cut out a bunch of stuff before the actual device name and the /show.version at the end.

Example:

Code:

cpever () {
	awk '/JUNOS/ && /boot/ {sub (/[^\/]* .$/, "", FILENAME); print $5 " " FILENAME}' 
~/svn/nw_config_data/*cpe.domain.net/show.version | sort -k5

Output:
[10.0R4.7] /home/clmbn-eng2/a/rwalker/svn/nw_config_data/device-r0.cpe.domain.net/show.version

I need to make /home/clmbn-eng2/a/rwalker/svn/nw_config_data/ and /show.version disappear so my output can go back to looking like this [10.0R4.7] device1-r0.cpe.domain.net
