'-mtime -10' syncs only files newer 10 days (-mtime is just one example, use whatever find expressions you need)

printf %P: File's name with the name of the command line argument under which it was found removed.

this way, you can use any src directory, no need to cd into your src directory first.

using \\0 in printf and a corresponding --from0 in rsync ensures that even filenames with newline characters work (thanks syssyphus for #3808).

both, #1481 and #3808 just work if you either copy the current directory (.) , or the filesystem root (/), otherwise the output from find and the source dir from rsync just don't match. #7685 works with an arbitrary source directory.

Consider using this cmd when:

1. You are planning to traverse a big directory.

2. There is a subdir you don't want find to decend to. (entirely ignore)

3. You don't want find to decend to any mounted filesystems under this dir.

* The -xdev flag tells find do not go to other filesystems.

* -path ./junk_dir -prune is the pattern to ignore ./junk_dir entirely.

* The rest is the typical search and print.

To ignore multiple subdirs, you can just iterate the pattern, e.g.

find . -path ./junk1 -prune -o -path ./junk2 -prune ...

If you do want to include other filesystems, then remove -xdev flag.

If you want to search files, then change -type d to -type f.

A quick find command to identify all TAR files in a given path, extract a list of files contained within the tar, then search for a given string in the filelist. Returns to the user as a list of TAR files found (enclosed in []) followed by any matching files that exist in that archive. TAR can easily be swapped for JAR if required.

recursively search dir for a a particular file type, search each file for a particular text.

Show the top file size in human readable form

Show the top 10 file size

Also:

* find . -type f -exec ls -s {} \; | sort -n -r | head -5

* find . -type f -exec ls -l {} \; | awk '{print $5 "\t" $9}' | sort -n -r | head -5

If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

-depth argument will cause find to do a "depth first" tree search, this will eliminate the "No such file or directory" error messages

Used this command recently to remove the trailing ?> from all the files in a php project, which has having some unnecessary whitespace issues. Obviously, change *.php to whatever you'd like.

Extract in the current directory the content of all parted archives.

Use the same password for each one.

expands through shell and not find

but may hits the limit of max argument size for rm

(thus: for f in **/*.htm;do rm $f;done

but then I prefer the find command ;)

In this way it doesn't have problems with filenames with spaces.

Returns any file in the folder which would be rejected by Gmail, if you were to send zipped version.

(Yes, you could just zip it and knock the extension off and put it back on the other side, but for some people this just isn't a solution)

Increase the modification date for the files selected with the find command.

Greater than 500M and sorted by size.

you can change the size :)

Some MP3s come with tags that don't work with all players. Also, some good tag editors like, EasyTAG output tags that don't work with all players. For example, EasyTAG saves the genre as a numeric field, which is not used correctly in Sansa MP3 players.

This command corrects the ID3 tags in MP3 files using mid3iconv, which comes with mutagen. To install Mutagen on Fedora use "yum install python-mutagen"

This command is recursive and will delete in all directories in ".". It will find and delete all files not specified with ! -name "pattern". In this case it's file extensions. -type f means it will only find files and not directories. Finally the -delete flag ask find to delete what it matches. You can test the command by running it first without delete and it will list the files it will delete when you run it.
