Insert Text after searching via grep
Hi Team,

I have a file with the following patterns:
Code:
 ==> xyz_Server_Started_with_Errors  <==
errors.

    ==> abc_Server_Started_with_Errors  <==
errors

  
==> reds_Server_Started_with_Errors  <==
errorss

I want them in this format:

Code:
===================================================
 ==> xyz_Server_Started_with_Errors  <==
===================================================

errors


===================================================

    ==> abc_Server_Started_with_Errors  <==
==================================================

errors


==================================================

  
==> reds_Server_Started_with_Errors  <==
==================================================

errorss

Thanks for the help Smilie

If a line contains pattern /Started_with_Errors/, then perform two substitution.

1. Add "=======...\n" at the beginning of line containing pattern /Started_with_Errors/
Code:
s/^/===================================================\
/

2. Add "\n=======..." at the end of the line containing pattern /Started_with_Errors/
Code:
s/$/\
===================================================/

===================================================
a\
===================================================
}' one.txt > two.txt
