find . -type f -size +1100000k |xargs -I% du -sh %
2010-01-31 22:04:07
User: 4fthawaiian
Functions: du find xargs

simple find -> xargs sort of thing that I get a lot of use out of. Helps find huge files and gives an example of how to use xargs to deal with them. Tested on OSX snow leopard (10.6). Enjoy.

find . -type f | parallel -j+0 grep -i foobar
2010-01-30 02:08:46
Functions: find grep

Parallel does not suffer from the risk of mixing of output that xargs suffers from. -j+0 will run as many jobs in parallel as you have cores.

With parallel you only need -0 (and -print0) if your filenames contain a '\n'.

Parallel is from https://savannah.nongnu.org/projects/parallel/

find directory/ -exec grep -ni phrase {} +
2010-01-28 12:15:24
User: sanmiguel
Functions: find grep
Tags: find grep

The difference between this and the other alternatives here using only grep is that find will, by default, not follow a symlink. In some cases, this is definitely desirable.

Using find also allows you to exclude certain files, eg

find directory/ ! -name "*.tmp" -exec grep -ni phrase {} +

would allow you to exclude any files .tmp files.

Also note that there's no need for calling grep recursively, as find passes each found file to grep.

find -type d -name ".svn" -prune -o -not -empty -type f -printf "%s\n" | sort -rn | uniq -d | xargs -I{} -n1 find -type d -name ".svn" -prune -o -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separate

User: 2chg
Functions: find md5sum sort uniq xargs

Improvement of the command "Find Duplicate Files (based on size first, then MD5 hash)" when searching for duplicate files in a directory containing a subversion working copy. This way the (multiple dupicates) in the meta-information directories are ignored.

Can easily be adopted for other VCS as well. For CVS i.e. change ".svn" into ".csv":

find -type d -name ".csv" -prune -o -not -empty -type f -printf "%s\n" | sort -rn | uniq -d | xargs -I{} -n1 find -type d -name ".csv" -prune -o -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separate
find -not -empty -type f -printf "%s\n" | sort | uniq -d | parallel find -type f -size {}c | parallel md5sum | sort | uniq -w32 --all-repeated=separate
2010-01-28 08:40:18
Functions: find md5sum sort uniq
Tags: xargs parallel

A bit shorter and parallelized. Depending on the speed of your cpu and your disk this may run faster.

Parallel is from https://savannah.nongnu.org/projects/parallel/

find filepath -type f -iname "*.html" -o -iname "*.htm" -o -iname "*.php" | xargs grep "Exception\|LGPL\|CODE1"
find directory/ |xargs grep -i "phrase"
find . -iname "*.jar" -exec cp '{}' /tmp/ \;
2010-01-26 12:19:15
Functions: cp find

Useful for Maven multimodule projects, where you want to extract all packaged jar files.

rsync -vd --files-from=<(find . -name entries -print ) . ../target_directory
2010-01-26 09:41:12
User: samyboy
Functions: find rsync

This command has been used to overwrite corrupted "entries" files of a corrupted subversion working copy.

Note the --files-from input format.

find . -maxdepth 1 -type d -exec 'mv "{}" "{}-old" && svnadmin create "{}" && svnadmin recover "{}-old" && svnadmin dump "{}-old" | svnadmin load "{}" && rm -rf "{}-old"' \;
find . -maxdepth 1 -type f| xargs sha1sum | sed 's/^\(\w*\)\s*\(.*\)/\2 \1/' | while read LINE; do mv $LINE; done
find -maxdepth 1 -type f -name "*.7z" -exec 7zr e '{}' ';'
2010-01-23 19:50:10
User: minnmass
Functions: find

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


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

would work, too.

find . -type f -exec stat \{\} \; | grep Modify: | awk '{a[$2]++}END{for(i in a){print i " : " a[i] }}' | sort
find . -exec grep -l "sample" {} \;
2010-01-16 13:12:52
User: whoami
Functions: find grep

Will find all files containing "sample" in the current directory and in the directories below.

find . -name "*.php" -exec grep -il searchphrase {} \;
2010-01-16 05:09:30
Functions: find grep

This is very similar to the first example except that it employs the 'exec' argument of the find command rather than piping the result to xargs. The second example is nice and tidy but different *NIXs may not have as capable a grep command.

find . -name "*.php" | xargs grep -il searchphrase
2010-01-14 22:42:36
User: refrax
Functions: find grep xargs

This command will find all files recursively containing the phrase entered, represented here by "searchphrase". This particular command searches in all php files, but you could change that to just be html files or just log files etc.

find . -type d -empty -delete
find . ! -name <FILENAME> -delete
2010-01-13 23:29:51
User: haplo
Functions: find
Tags: files rm

it will remove everything except the file names matching you can use also use wildcards

find / \( -local -o -prune \) \( -perm -4000 -o -perm -2000 \) -type f -exec ls -l {} \;
find /lib/modules/`uname -r`/ -type f -iname '*.o' -or -iname '*.ko' |grep -i -o '[a-z0-9]*[-|_]*[0-9a-z]*\.ko$' |xargs -I {} echo '# {}' >>/etc/modules.autoload.d/kernel-2.6
2010-01-13 02:12:08
User: paragao
Functions: echo find grep xargs

Whenever you compile a new kernel, there are always new modules. The best way to make sure you have the correct modules loaded when you boot is to add all your modules in the modules.autoload file (they will be commented) and uncomment all those modules you need.

Also a good way to keep track of the available modules in your system.

For other distros you may have to change the name of the file to /etc/modprobe.conf

find / -name *.conf | tee salida
i=0; for f in $(find ./ -size -10M -exec stat -c %s {} \; ); do i=$(($i + $f)); done; echo $i
find /path/to/images -name '*.JPG' -exec bash -c 'mv "$1" "${1/%.JPG/.jpg}"' -- {} \;
2010-01-07 15:41:17
User: sorpigal
Functions: bash find
Tags: bash find mv

Recursively rename .JPG to .jpg using standard find and mv. It's generally better to use a standard tool if doing so is not much more difficult.

sudo find /etc/rc{1..5}.d -name S99myservice -type l -exec sh -c 'NEWFN=`echo {} | sed 's/S99/K99/'` ; mv -v {} $NEWFN' \;
2010-01-03 00:56:57
User: zoomgarden
Functions: find mv sed sh sudo

Change run control links from start "S" to stop "K" (kill) for whatever run levels in curly braces for a service called "myservice". NEWFN variable is for the new filename stored in the in-line shell. Use different list of run levels (rc*.d, rc{1,3,5}.d, etc.) and/or swap S with K in the command to change function of run control links.

find /path/to/images -name '*.JPG' -exec rename "s/.JPG/.jpg/g" \{\} \;
2010-01-02 19:12:37
User: renich
Functions: find rename
Tags: find rename

This command is useful for renaming a clipart, pic gallery or your photo collection. It will only change the big caps to small ones (on the extension).
