Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

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.

Comment by sevrinsky 396 weeks and 2 days ago

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.
