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

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

find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g'
2009-03-12 22:25:26
Functions: find sed

NOT MINE! Taken from hackzine.com blog.

It creates a tree-style output of all the (sub)folders and (sub)files from the current folder and down(deeper)

Quoting some of hackzine's words

"Murphy Mac sent us a link to a handy find/sed command that simulates the DOS tree command that you might be missing on your Mac or Linux box. [..split...] Like most things I've seen sed do, it does quite a bit in a single line of code and is completely impossible to read. Sure it's just a couple of substitutions, but like a jack in the box, it remains a surprise every time I run it."

find . -maxdepth 1 -type f -print0 | xargs -0 -i cp ./{}{,.bak}
2009-03-12 16:02:13
User: voyeg3r
Functions: cp find xargs

"." 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

find . -name *DS_Store -exec echo rm {} \;
2009-03-11 11:30:55
User: dgomes
Functions: echo find rm

This is quite usefull in Unix system share via NFS or AppleTalk with OSX clients that like to populate your filesystem with these pesky files

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.

find . -name .DS_Store -exec rm {} \;

Recursively removes all those hidden .DS_Store folders starting in current working directory.

find . -iname "*wav" > step1 ; sed -e 's/\(^.*\)wav/\"\1wav\" \"\1mp3\"/' step1 > step2 ; sed -e 's/^/lame /' step2 > step3 ; chmod +x step3 ; ./step3

This command will delete files i a given path (/dir_name) , which older than given time in days (-mtime +5 will delete files older than five days.

find . -type f -iname '*.wmf' | while read FILE; do FILENAME="${FILE%.*}"; wmf2svg -o ${FILENAME}.svg $FILE; done
2009-03-07 22:21:01
User: atoponce
Functions: find read

This assumes you have the package installed necessary for converting WMF files. On my Ubuntu box, this is libwmf-bin. I used this command, as libwmf is not on my wife's iMac, so I archived the directories containing the WMF files from OS X, ran them on my Ubuntu box, archived the resulting SVGs, and sent them back to her. Quick, simple and to the point.

Searches directories recursively looking for extensions ignoring case. This is much more readable and clean than -exec for find. The while loop also gives further flexibility on complex logic. Also, although there is 'wmf2svg --auto', it expects lowercase extensions, and not uppercase. Because I want to ignore case, I need to use the -o option instead.

Works in ZSH and BASH. Haven't tested in other shells.

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

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
2009-03-04 16:41:02
User: microft
Functions: find gawk sort stat xargs

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

Ordered from most recent to older.

find . -type d -name DIR -print0 | xargs -r0 rm -r
2009-03-04 14:49:21
User: miguelbaldi
Functions: find rm xargs
Tags: svn cvs

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

find . -type f | wc -l
logs=$(find . -name *.log);for log in $logs; do cat /dev/null > $log;done
2009-03-04 10:05:48
Functions: cat find

This find files of name like *.log and truncates them.

find / -name "*.jpg" -print -exec rdjpgcom '{}' ';'
2009-03-03 02:13:44
User: Williebee
Functions: find

Finds comments in jpg files, but I can't figure out how to exclude (in output) files without comments.

sudo find / -type f \( -perm /4000 -a -user root \) -ls -o \( -perm /2000 -a -group root \) -ls
2009-03-02 18:48:17
User: atoponce
Functions: find sudo

Discovering all executables on your system that can be run as another user, especially root, is critical for system security. The above command will find those files with have SUID or SGID bits set and are owned by the root user or group.

find <top_level_dir> -depth -type d -empty -exec rmdir -v {} \;
find -type -f -exec cp {} {}.bak \;
find . -type f | while read file; do cp $file ${file}.bak; done
2009-03-01 23:42:49
User: atoponce
Functions: cp find read

This is a simple case of recursing through all directories, adding the '.bak' extension to every file. Of course, the 'cp $file $file.bak' could be any code you need to apply to your recursion, including tests, other functions, creating variables, doing math, etc. Simple and clean recursion.

sudo find / -mmin 60 -type f
2009-03-01 23:03:31
User: atoponce
Functions: find sudo

Useful mainly for debugging or troubleshooting an application or system, such as X11, Apache, Bind, DHCP and others. Another useful switch that can be combined with -mmin, -mtime and so forth is -daystart. For example, to find files that were modified in the /etc directory only yesterday:

sudo find /etc -daystart -mtime 1 -type f
