simple sed question

jaykup · 01-24-2008, 08:11 AM

I want to run a sed script only on the lines that contain "^http"

sed '/^http/ {-f urlencode.sed}' list.m3u

doesn't work.. what do I need to do?

sed -f urlencode.sed list.m3u

In the sed script include commands that only operate on lines starting with "http" for example:
/^http/s/dogs/cats/g
/^http/s/horses/pigs/g

Thanks! That makes perfect sense now.

"If you see the "read" command in a bash script, it is probably wrong."

Love it! As a long time ksh fan, I have been waiting a zillion years for the oh so whizbang bash and zsh to catch up wrt read and having sleep built-in and others ...
