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.

sudo pacman -Rns packagename
2011-03-20 21:07:14
User: ibnarrashid
Functions: sudo

Removes the package, 'packagename' in the example ,from your system. '-R' is the actual removal option, 'n' is for removing backup configuration files saved by pacman, and 's' is for removing the dependencies of the given package which are not required by other packages. pacman does not remove configuration files, etc. created by the package.

Functions: sort
Tags: Network

Prevents the need for the grep & awk statements. Sort is optional if you don't care about the output order. The network range can also be specified as in the original post.

-A Display targets by address rather than DNS name. (Probably unnecessary...)

-a Show systems that are alive.

Repeat the previously used command (!!) until it exits with a success code (0). To put a delay between attempts you could do something like

until !!; do sleep 5; done

to wait 5 seconds after each attempt.
