I have not idea how I would accomplish this. I have a script that scans for CDP neighbours. I get the results in a file. I am interested in CDP Neighbor Details if name BSWITCH shows up. If BSWITCH is not present then skip.

10.201.242.1      core              Tunnel20               cisco ASR1004

I would like the results to read.

It depends how you want to filter, including what you want or excluding what you don't want.

The simplest might be to use grep -Ev with an expression matching the records you want to exclude.

If you are not bothered about the titles in the report, it would be easier to use grep BSWITCH in your code.

What have you got so far that we can help with?
