The command that i am trying is :

awk /SACHHYAWebMonaco/ MyFile.txt

Using this command, I am able to get that particular line in which my string is present. Here is the result of the awk command :

SACHHYAWebMonaco                          Release/MR1_2019/3.0.7-570+36a238d

What I want to grep is only “3.0.7” (which is the version) from that line .

Can anyone have any suggestion to do that?

Answer

You can use / and - as field separators and print the third field.

This assumes the format of the lines and position of the information you seek will always be such.

$ awk -F[/-] '/SACHHYAWebMonaco/ {print $3}' file
3.0.7
