Hi,

I'm looking for a sed command, which wil place a text before every line that doesn't start with a colon (:) exept for the first 3 lines. Can anybody help me? Thanx in advance.

Hi Kurumi,

thanx for your reply! It works, but there is 1 import thing that does not work: Only the lines that do not start with : must be altered. Do you have a salution? Thanx

Hi Kurumi,

I have found the previous problem. But I have a new one: the command replaces the first character of the line. I don't want this to happen. The line must stay intact.

the least you could is to provide samples for input file and output you need.

Hi Kurumi,

have tested this? When I try it I get " sed:Command garbled: 4,${/^[^:]/s/^/:86:/}

OH, never mind It works on Ubuntu. I think it is a version problem.

Hi Kurumi,

Thank you very much for helping me out. The only thing I had to change on SCO was using gwxsed instead of sed.
