Display a File with Line Number

The nl command lists the contents of a file where is each line is prefixed by a line number. For more information about this command, check out its man page. I tested under Mac OS X and Xubuntu 9.04

What others think

You can also use "cat -n filename"

Much easier just to use "less -N". -N can also be turned off and on while in an existing less session.

The best feature to nl in my opinion is that you can give it a regex to only number certain lines with the -p option.

I often use nl when I want to number some lines of text that I am editing in vim. Here's how to use nl to do that: select the lines of text you want to number, and in command ':' mode enter '! nl' and the vim command line will look like this:

:'<,'>! nl

the exclamation point tells vim to filter the selection through the following shell command, which is 'nl' in this case.
