I've put together a short writeup on what kind of newness you can expect from the next iteration of clfu. Check it out here.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

"." 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

svn status | grep "^\?" | awk '{print $2}' | xargs svn add
2009-03-12 15:06:12
User: unixfu73000
Functions: awk grep xargs
Tags: svn

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
2009-03-10 17:01:40
User: Highwayman
Functions: awk grep rm xargs

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
2009-03-09 22:08:45
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 .
2009-03-09 18:11:35
User: Viaken
Functions: find xargs

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
find /usr/lib -maxdepth 1 -type l -print0 | xargs -r0 du -Lh
2009-03-07 00:17:45

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
2009-03-05 21:26:24
User: starchox
Functions: find xargs
Tags: bash

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

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

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. ^_^

rpm -qa | grep PACKAGENAME | xargs rpm -q --filesbypkg
2009-02-26 14:32:12
User: piscue
Functions: grep rpm xargs

rpm, sometimes, is not wildcard friendly. To search files installed from package this could be useful.

change PACKAGENAME to any package do you want to search

svn st | grep ^? | xargs svn add 2> /dev/null
echo COMMAND | xargs -ixxx ps -C xxx -o pid= | xargs -ixxx ls -l /proc/xxx/cwd
find . -type f -name "*.java" -print0 | xargs -0 -n 1 svn blame | sed -n 's/^[^a-z]*\([a-z]*\).*$/\1/p' | sort | uniq -c | sort -n
find . -name "*.php" | xargs egrep -i -s 'specialFunction' > searchresult.txt
2009-02-23 15:25:49
User: tb323
Functions: egrep find xargs

Will search recursively and output the searchResult.txt in the same folder you are located.

2009-02-21 02:31:24
User: laburu
Functions: awk cat grep ls sed xargs

Note that the file at the given path will have the contents of the (still) deleted file, but it is a new file with a new node number; in other words, this restores the data, but it does not actually "undelete" the old file.

I posted a function declaration encapsulating this functionality to http://www.reddit.com/r/programming/comments/7yx6f/how_to_undelete_any_open_deleted_file_in_linux/c07sqwe (please excuse the crap formatting).

This is a nice way to kill processes.. the example here is for firefox!!! substitute firefox for whatever the process name is...
