find ~/.thumbnails/ -type f -atime +30 -print0 | xargs -0 rm

By time thumbnail images in ~/thumbnails take up too much space, this command will help deleting old ones.

Find options explained:

-type f : find files only, not directories

-atime +30 : last accessed more than 30 days ago

Can be used for other commands as well, replace rm with ls.

It is easy to make this shorter but if the filenames involved have spaces, you will need to do use find's "-print0" option in conjunction with xargs's "-0" option. Otherwise the shell that xargs uses to execute the "rm" command line will treat the space as a token separator, thereby treating the name as two (or more) names.

ps ax | grep <processname> | grep -v grep | awk '{print $1}' | sudo xargs kill -9

Create backup (.tar.gz) for all first-level directory from current dir.

-t, --target-directory=DIRECTORY (copy all SOURCE arguments into DIRECTORY).

This command will kill all processes using a directory. It's quick and dirty. One may also use a -9 with kill in case regular kill doesn't work. This is useful if one needs to umount a directory.

find . -maxdepth 1 -type f -print0 | xargs -0 -i cp ./{}{,.bak}

"." is current dir, maxdepth is the level, -print0 | xargs -0 fix spaces in names, -i interactive , ./ is the current dir {} actual name , and {,.bak} is the atual name + bak

This adds all new files to SVN recursively. It doesn't work for files that have spaces in their name, but why would you create a file with a space in its name in the first place?

svn status | grep ^? | awk '{print $2}' | xargs rm -rf

Removes all unversioned files and folders from an svn repository. Also:

svn status --no-ignore | grep ^I | awk '{print $2}' | xargs rm -rf

will remove those files which svn status ignores. Handy to add to a script which is in your path so you can run it from any repository (a la 'svn_clean.sh').

sudo find / -iname "*.lproj" -and \! -iname "en*" -print0 | tee /dev/stderr | sudo xargs -0 rm -rfv

User: asmoore82
Functions: find rm sudo tee xargs

This will get the job done in the most efficient way -

spawning only one `rm` process.

"On-the-fly" find data is displayed through `tee` and

you should have plenty of time to ctrl-c if needed before it's too late.

You may need to re-run this after major Software Updates.

To leave more languages in, add more ``-and \! -iname "lang*"'' statements:

sudo find / -iname "*.lproj" -and \! -iname "en*" -and \! -iname "spanish*" -print0 | tee /dev/stderr | sudo xargs -0 rm -rfv

**Edit: note the 2nd sudo near the end of the pipeline - this is necessary.

find . -iname \*.mp3 -print0 | xargs -0 mp3gain -krd 6 && vorbisgain -rfs .

Run this in the directory you store your music in.

mp3gain and vorbisgain applies the ReplayGain normalization routine to mp3 and ogg files (respectively) in a reversible way.

ReplayGain uses psychoacoustic analysis to make all files sound about the same loudness, so you don't get knocked out of your chair by loud songs after cranking up the volume on quieter ones.

ls -1 *.part1.rar | xargs -d '\n' -L 1 unrar e

You also can sum the file usage of all files

find /usr/lib -maxdepth 1 -type l -print0 | xargs -r0 du -Lch
find . -type d \( -name DIR1 -o -name DIR2 \) -prune -o -type f -print0 | xargs -r0 md5sum

Useful if you want get all the md5sum of files but you want exclude some directories. If your list of files is short you can make in one command as follow:

find . -type d \( -name DIR1 -o -name DIR2 \) -prune -o -type f -exec md5sum {} \;

Alternatively you can specify a different command to be executed on the resulting files.

find . -type f -print0 | xargs -r0 stat -c %Y\ %n | sort -rn | gawk '{sub(/.\//,"",$2); print $2}' > /tmp/playlist.m3u

I use this to generate a playlist with all the podcasts I listen to.

Ordered from most recent to older.

You can use this command to delete CVS/svn folders on given project.

ps axww | grep SomeCommand | awk '{ print $1 }' | xargs kill
2009-02-28 17:48:51
User: philiph
Functions: awk grep ps xargs
-7

This command kills all processes with 'SomeCommand' in the process name. There are other more elegant ways to extract the process names from ps but they are hard to remember and not portable across platforms. Use this command with caution as you could accidentally kill other matching processes!

xargs is particularly handy in this case because it makes it easy to feed the process IDs to kill and it also ensures that you don't try to feed too many PIDs to kill at once and overflow the command-line buffer.

Note that if you are attempting to kill many thousands of runaway processes at once you should use 'kill -9'. Otherwise the system will try to bring each process into memory before killing it and you could run out of memory. Typically when you want to kill many processes at once it is because you are already in a low memory situation so if you don't 'kill -9' you will make things worse

svn status | grep '^\?' | sed -e 's/^\?//g' | xargs svn add
2009-02-28 03:00:28
User: dollyaswin
Functions: grep sed xargs
0

These part of the command:

svn status | grep '^\?' => find new file or directory on working copy

sed -e 's/^\?//g' => remove "^" character on the first character of file name

xargs svn add => add file to subversion repository

You can modify above command to other circumtances, like revert addition files or commit files that have been modified. ^_^
