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.

ls -a | sed "s#^#${PWD}/#"

Functions: ls sed
Tags: sed ls pwd

Use the -a flag to display all files, including hidden files. If you just want to display regular files, use a -1 (yes, that is the number one). Got this by RTFM and adding some sed magic.

[bbbco@bbbco-dt ~]$ ls -a | sed "s#^#${PWD}/#"











[bbbco@bbbco-dt ~]$ ls -1 | sed "s#^#${PWD}/#"

adobe updater keeps popping up. (normal update fails, probably due to insufficient rights)

I think it would be wise if anyone voting down left a comment indicating the reason for that action. Don't keep it to yourself. Thanks.

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know

screen -d -m nautilus --no-desktop `pwd`
2009-05-07 00:49:07
User: windsurfer
Functions: screen

This opens up nautilus in the current directory, which is useful for some quick file management that isn't efficiently done from a terminal.

User: ringlerun
Functions: chmod find

sometimes if directories are too deep, chmod -R fails... in those cases, a find comes in most handy :)

sudo chmod -x /usr/lib/notify-osd/notify-osd

User: lokutus25
Functions: chmod sudo

Quick and dirty way to disable the Ubuntu notifications that can be quite annoying. It prevent the notify-osd to start so you need to logout Gnome or kill it by hand to take effect.

This should work on any RPM-based distribution. It's more reliable than trying to parse the content of the files.

Functions: pwd

Simply displays your current working directory. Helps when you are buried deep in /etc or some other obscure place.
