Append a line to a file

CJenR

Hey!

I am trying to append few lines to a txt file after a pattern match. I can append it if I find a match but problem is, I want to skip two more lines after I found the match and then insert those new lines.

I used SED to append: sed -i -e "/pattern/ a\ new lines" /file_name

Can someone give me some ideas.
