how to remove a substring
I want to modify a string in shell script (/bin/sh). Could you please help me.
I have a variable which can store the values like below.
v10.5.2.1p001C_TN1
or v10.5.2.1p002_TN1
I have to search first whether ‘p' character exists into the string which is stored in a variable.. If yes, then I have to remove the “p001C” and “p002' correspondingly. I mean I have to remove the content from p and before _TN
Thanks in advance.
