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/

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.

find . -mtime +30 -exec mv {} old/ \;

Use find's built-in "exec" option to avoid having to do any weirdness with quoting.

cd ~/wallpapers; feh --bg-fill "$( ls | sort -R | head -n 1 )"

don't bother spawning a bc process or counting the number of options, just pick a random one.

'sort -R' sorts randomly, so pick the top one.

find . -name '*.jpg' -o -name '*.JPG' -print0 | xargs -0 mogrify -resize 1024">" -quality 40
2013-06-20 16:09:41
User: minnmass
Functions: find xargs
0

The "find $stuff -print0 | xargs -0 $command" pattern causes both find and xargs to use null-delineated paths, greatly reducing the probability of either hiccuping on even the weirdest of file/path names.

It's also not strictly necessary to add the {} at the end of the xargs command line, as it'll put the files there automatically.

Mind, in most environments, you could use find's "-exec" option to bypass xargs entirely:

find . -name '*.jpg' -o -name '*.JPG' -exec mogrify -resize 1024">" -quality 40 {} +

will use xargs-like "make sure the command line isn't too long" logic to run the mogrify command as few times as necessary (to run once per file, use a ';' instead of a '+' - just be sure to escape it properly).

ls "~/Music/iTunes/iTunes Media/Mobile Applications" > filepath

Functions: ls

This will generate the same output without changing the current directory, and filepath will be relative to the current directory.

Note: it will (still) fail if your iTunes library is in a non-standard location.

find . -name .svn -type d -exec rm -rf '{}' +

User: minnmass
Functions: find rm

With the plus instead of semicolon, find builds the (eg.) rm command like xargs does - invokes as few extra processes as possible.

wget -k $URL

User: minnmass
Functions: wget
Tags: wget
-2

The "-k" flag will tell wget to convert links for local browsing; it works with mirroring (ie with "-r") or single-file downloads.

find -maxdepth 1 -type f -name "*.7z" -exec 7zr e '{}' ';'
2010-01-23 19:50:10
User: minnmass
Functions: find
-1

Use find's built-in ability to call programs.

Alternatively,

find -maxdepth 1 -type f -name "*.7z" -print0 | xargx -0 -n 1 7zr e

would work, too.
