This pipeline will find, sort and display all files based on mtime. This could be done with find | xargs, but the find | xargs pipeline will not produce correct results if the results of find are greater than xargs command line buffer. If the xargs buffer fills, xargs processes the find results in more than one batch which is not compatible with sorting. Note the "-print0" on find and "-0" switch for perl. This is the equivalent of using xargs. Don't you love perl? Note that this pipeline can be easily modified to any data produced by perl's stat operator. eg, you could sort on size, hard links, creation time, etc. Look at stat and just change the '9' to what you want. Changing the '9' to a '7' for example will sort by file size. A '3' sorts by number of links.... Use head and tail at the end of the pipeline to get oldest files or most recent. Use awk or perl -wnla for further processing. Since there is a tab between the two fields, it is very easy to process. Show Sample Output

If you give tar a list of filenames, it will not add the directories, so if you don't care about directory ownership or permissions, you can save some space. Tar will create directories as necessary when extracting. This command is limited by the maximum supported size of the argument list, so if you are trying to tar up the whole OS for instance, you may just get "Argument list too long".

This command has been used to overwrite corrupted "entries" files of a corrupted subversion working copy. Note the --files-from input format.

Gives you a list for all installed chrome (chromium) extensions with URL to the page of the extension. With this you can easy add a new Bookmark folder called "extensions" add every URL to that folder, so it will be synced and you can access the names from every computer you are logged in. ------------------------------------------------------------------------------------------------------------------ Only tested with chromium, for chrome you maybe have to change the find $PATH.

Lists a sample of all installed toilet fonts Show Sample Output

use -iname \*[.ch] instead of -iname \*.c -o -iname \*.h

Preserve file structure when coping and exclude some file o dir patterns Show Sample Output

Maybe not clean with big package and too long argument. But return every file who can be executed.

With the plus instead of semicolon, find builds the (eg.) rm command like xargs does - invokes as few extra processes as possible.

Also looks in subfolders

You can compare directories on two different remote hosts as well: diff -y <(ssh user1@host1 find /boot|sort) <(ssh user2@host2 find /boot|sort) To avoid password-prompt on remote host just generate the rsa key locally and copy it to remote host: ssh-keygen -t rsa then ssh you@server1 "mkdir .ssh" then scp .ssh/id_rsa.pub you@server1:; .ssh/authorized_keys2

Output of this command is the difference of recursive file lists in two directories (very quick!). To view differences in content of files too, use the command submitted by mariusbutuc (very slow!): diff -rq path_to_dir1 path_to_dir2 Show Sample Output

This is much safer than using -L, because it will not follow links that point to places outside the target directory subtree (CWD, in this case). See here for explanation: http://unix.stackexchange.com/a/38691/9382

basic find implementation for systems that don't actually have find, like an android console without busybox installed.
