find . -type f -exec grep StringToFind \{\} --with-filename \;|sed -e '/svn/d'|sed -e '/~/d'

User: f241vc15
Functions: find grep sed

Look for a string in one of your codes, excluding the files with svn and ~ (temp/back up files). This can be useful when you're looking for a particular string in one of your source codes for example, inside a directory which is under version control (e.g. svn), removing all the annoying files with ~ (tilde) from the search. you can even change the command after -exec to delete (rm) or view (cat) files found by 'find' for example

find ~/.thumbnails/ -type f -atime +30 -print0 | xargs -0 rm
2009-03-30 04:23:07
User: alperyilmaz
Functions: find xargs

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

find /home/user/doc/ -type d -printf "mkdir -vp '/home/user/Dropbox%p'\n" -o -type f -printf "ln -vs '%p' '/home/user/Dropbox%p'\n" | sh

User: jnash
Functions: find

Extremely useful to maintain backups if you're using Dropbox. This mirrors the entire directory structure and places symlinks in each to the original file. Instead of copying over the data again to the ~/Dropbox folder creating a symbolic link tree is much more sensible in terms of space usage.

This has to be supplemented by another script that removes dead symlinks in the Dropbox folder which point to files that have been moved/removed.

find -L ./ -type l -delete

And then removing empty directories

find ./ -type d -exec rmdir 2>/dev/null {} \;

**Actually after some finding I found lndir which creates symbolic trees but it wasn't in the Arch repos so.. ;)

find ./ -name '*.JPG' -type f -execdir rename -f 'y/A-Z/a-z/' {} \+

User: pronoiaque
Functions: find rename

Change files case, without modify directories, recursively.

... fucking vfat

find ./ -iname "*.mp3" -type f -printf "mv '%p' '%p'\n" | sed -e "s/mp3'$/mp3'/I" | sh
2009-03-27 13:42:40
User: jnash
Functions: find sed

Extensible to other ugly extensions like *.JPG, *.Jpg etc..

Leave out the last pipe to sh to perform a dry run.

find . -name 'junkfiles-*' -print0 | xargs -0 rm
2009-03-26 15:38:42
User: kancer
Functions: find xargs
Tags: find xargs print rm

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.

find . -type f -depth -3 -mtime -5
2009-03-25 19:54:06
User: totoro
Functions: find

Ever wanted to find the most recently modified files, but couldn't remember exactly where they were in a project directory with many subdirectories? The "find" command, using a combination of "-mtime -N" and "-depth -D" can be used to find those files. If your directory structure isn't very deep, just omit the "-depth -D", but if your directory structure is very deep, then you can limit the depth of the traversal using "-depth -D", where "D" is the maximum number of directory levels to descend.

faster than lsof by at least x2 on my box.

find . -wholename './.snapshot' -prune -o -print

User: jeffaz
Functions: find

This can be useful for those who have mounted NetApp file-systems with snapshot activated.

find -depth . | (while read FULLPATH; do BASENAME=`basename "${FULLPATH}"`; DIRNAME=`dirname "${FULLPATH}"`; mv "${DIRNAME}/${BASENAME}" "${DIRNAME}/${BASENAME// /_}"; done)

User: mohan43u
Functions: find mv read

Takes filenames and directory names and replace space to '_'.

date -d "@$(find dir -type f -printf '%C@\n' | sort -n | sed -n "$(($(find dir -type f | wc -l)/2))p")" +%F

User: allengarvin
Functions: date dir find wc

I needed to get a feel for how "old" different websites were, based on their directories.

find . -regex "[^.]*" -depth -empty -type d -mtime +1 -exec rmdir -v {} \;
find / -nouser -o -nogroup -print
find -iname '*.flac' | sed 's:/[^/]*$::' | uniq
2009-03-24 13:26:31
User: ar
Functions: find sed

Run this in your music folder, or give the path directly after "find".

The sed pattern filters away the basename.

find ./ -mtime -5 | xargs rm -f
find . -name *.php | xargs grep -i -n 'TERM'
find . -name "*.EXT" | xargs grep -n "TODO" | wc -l
find -maxdepth 1 -type d -print0 | xargs -0 -I {} tar -cvzf {}.tar.gz {}
2009-03-17 11:12:53
User: piemme
Functions: find tar xargs

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

find ~/project -mtime -1 -type f -print | tar jcvf myfiles.tar.bz2 -T -
2009-03-13 13:03:11
User: voyeg3r
Functions: find tar

create tar.bz2 package from files "-type f" modificated today "-mtime -1" in ~/project

rsync -avz -e ssh --files-from=<(find -mtime +30 -mtime -60) source dest
2009-03-13 12:58:28
User: voyeg3r
Functions: find rsync ssh

rsync from source to dest all between >30

find . -name "*.pdf" -print0 | xargs -0 cp -t downloads/
2009-03-13 03:15:27
User: abcde
Functions: cp find xargs

-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.
