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.

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.

Watch contents of a file grow

Terminal - Watch contents of a file grow

Watch contents of a file grow

In this case, I'm keeping an eye on /var/log/messages, but of course any file will do. When I'm following a file, I generally don't want to see anything other than what has been added due to the command or service I've executed. This keeps everything clean and tidy for troubleshooting.


There are 2 alternatives - vote for the best!

What others think

Never thought about that. It's true when you monitor a log file, only new lines are of any interest !

Good idea :)

You can use it without "-n 0".

Just tap enter several times to get some free space between

old and new lines. This might be helpful by watching logfiles

- while - they grow.

I find it useful to associate this with screen splitting in screen. From within a screen session :

^A S : split the screen

tail -n 0 -f /var/log/syslog

^A ^I : focus on the second panel

^A ^C : create a new screen session in the panel

Do your actions in the second panel while you watch your file in the panel on top. Use ^A ^I to switch between panels.

@raphink why not use Yakuake

and you have your log to your right and you can keep executing commands in your left.
