Question

I’m stumped with how to remove a portion of a string that has forward slashes and question marks in it.

Example: /diag/PeerManager/list?deviceid=RXMWANT8WFYJNF7K6DXXXJLJVN

and I need the output to be RXMWANT8WFYJNF7K6DXXXJLJVN

I’ve tried tr and sed but tr removes some of the characters I need in the output. sed is giving me trouble because of the forward slashes.

What’s a quick method to remove the /diag/PeerManager/list?deviceid= portion of my string?
thanks!

Answer 1

This worked for me:

sed 's/.*deviceid=\([^&]*\).*/\1/'

Example:

$ echo '/diag/PeerManager/list?deviceid=RXMWANT8WFYJNF7K6DXXXJLJVN' | sed 's/.*deviceid=\([^&]*\).*/\1/'
RXMWANT8WFYJNF7K6DXXXJLJVN

This is not the most robust solution, but if you have a fixed set of input that will never change, it’s probably good enough.
