What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get involved!

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.

Universal configuration monitoring and system of record for IT.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

Print just line 4 from a textfile

Terminal - Print just line 4 from a textfile
head -n X | tail -n 1

Functions: head tail
Print just line 4 from a textfile

using tail first won't do it because tail counts from the bottom of the file. You could do it this way but I don't suggest it


There is 1 alternative - vote for the best!

Terminal - Alternatives
sed -n '4p'
2010-07-08 22:07:40
User: infinull
Functions: sed

this method should be the fastest

sed -n '4{p;q}'
awk 'NR==4'
sed '4!d'
2011-09-05 17:54:57
User: totti
Functions: sed

d --> delete

!d ---> delete others

perl -ne '$. == 4 && print && exit'
2011-09-05 21:52:16
User: bashrc
Functions: perl

Perl version - just for completeness sake ;)

Know a better way?

If you can do better, submit your command here.

What others think

Oops, of course you are right infinull, I described it wrong, my line does indeed print the fourth latest line of the file..

I knew it could be done in a better way then I did it, thanks guys
