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.

- 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.
Terminal - Commands by bandit36 - 3 results
You can use this to loop any command to periodically see the output.
while true; do [YOUR COMMAND HERE]; sleep [# of seconds]; done;
Alternatively, you can put it in a simple shell script to save typing!
#/!bin/bash
while true; do $1; sleep $2; done;
/path/to/script.sh "ifconfig eth0 | grep 'inet addr:'" 60
populate the auth.hosts file with a list of IP addresses that are authorized to be in use and when you run this command it will return the addresses that are pingable and not in the authorized list.
Can be combined with the "Command line Twitter" command to tweet unauthorized access.
This will create an exact duplicate image of your hard drive that you can then restore by simply reversing the "if" & "of" locations.
sudo dd if=/media/disk/backup/sda.backup of=/dev/sda
Alternatively, you can use an SSH connection to do your backups:
dd if=/dev/sda | ssh [email protected] dd of=~/backup/sda.backup
