If you're on a system that doesn't have nl, you can use cat -n.


There is 1 alternative - vote for the best!

Write each FILE to standard output, with line numbers added. With no FILE, or when FILE is -, read standard input.

What others think

On debian/ubuntu, nl comes in the same package as cat (coreutils), so it will always be available there. If you just want to count, grep has a count option:

ps aux | grep -c [h]ttpd

I'm on MacOS 10.3.9 (darwin/bsd) which doesn't include nl. Looks like it was included as of MacOS 10.4. Thanks, I forgot about grep's line number option. The -c option prints just the line number. The -n option will include the the matched line as well.
