Folks: Been a while since I posted last, and I require a little pointing in the right direction - I am looking for a very simple solution, which removes lines that 'do not' match my criteria. I have a Expect script which dumps into a few generic devices, and logs out the session; however, I only want a few lines of the output. With the latter in mind - I have tried to fine tune my logging session for Expect; however, for some odd reason I must capture the entire session - otherwise nothing is captured. Due to the latter, I thought this would be a good exercise to learn more perl.

Expect session output = logout.txt

00:eb:99:33:bc:2c    some string of text
00:eb:99:33:bc:2c   Tx        -.34  32423
00:eb:99:33:bc:2c  null
device log entries are empty - log service did not start
98:ab:34:12:ac:3c   Rx  critical
Tx critical   00:eb:99:33:bc:2c
device log entries are full 00:eb:99:33:bc:2c

The output is not formatted any particular way due to embedded firmware. What I am hoping to do is remove the lines, which do not have a MAC address in them. I am thinking I can do something like 0-1|a-e: 0-1|a-e: 0-1|a-e: 0-1|a-e:~ To match the MAC address format. Looking for direction on how to do this - I have no clue where to start, or what to look for. Thank you JW
