How can I catch the text in specific table which is seen with another code on cli? Or how to catch the text in same design another way?

That is sample table

***pool-name             subnet               mask-len  vr-id
--------------------  -------------------  --------  -----
dataoam               10.254.140.160       27        0***

and I need a dataoam

Answer 1

It is a bit unclear which command you are using, ("networking show all..." does not name an actual command on my system), but assuming a given command yields your output, you can use tail and awk:

<your command> | tail -n +3 | awk '{print $1}'

Example:

jvc@BlueBuilder:~$ cat out.txt
***pool-name             subnet               mask-len  vr-id
--------------------  -------------------  --------  -----
dataoam               10.254.140.160       27        0***

and

jvc@BlueBuilder:~$ cat out.txt | tail -n +3 | awk '{print $1}'
dataoam
