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.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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.

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

As is, this runs until shutdown. Output of pgrep could be banished to /dev/null (current usage loops the pid to terminal)

while pgrep wget > /dev/null 2>&1 || sudo shutdown -P now; do sleep 1m; done

could be expanded to do something every time the process is not-running (e.g. re-spawn/keep-alive)

while pgrep gcalctool > /dev/null 2>&1 || gcalctool ; do sleep 0.1s; done

and, just in case one wants to use this for a single catch of a program stopping (e.g. notify when this process finishes this time) a break could be inserted to stop the looping

while pgrep wget > /dev/null 2>&1 || { zenity --info --text="wget is finished"; break; }; do sleep 1m; done

^example assumes zenity but one could also use notify-send, mail, whatever...
