The same as the other user, but smarter, using -d and -f

default stack size is 10M. This makes your multithread app filling rapidly your memory. on my PC I was able to create only 300thread with default stack size. Lower the default stack size to the one effectively used by your threads, let you create more. ex. putting 64k I was able to create more than 10.000threads. Obviously ...your thread shouldn't need more than 64k ram!!!

Converts the batch of images to video. *mencoder* required.

Plays the sound of the file, should sound like *some* kind of music, most files sound like static but some are really cool. variations: sudo cat /dev/sda > /dev/dsp sudo cat /dev/sda5 | aplay Check out http://bbs.archlinux.org/viewtopic.php?id=70937 for more variations! semi-dupe--like http://www.commandlinefu.com/commands/view/985/generate-white-noise but with different syntax and program.

Having to escape forwardslashes when using sed can be a pain. However, it's possible to instead of using / as the separator to use : . I found this by trying to substitute $PWD into my pattern, like so sed "s/~.*/$PWD/" file.txt Of course, $PWD will expand to a character string that begins with a / , which will make sed spit out an error such as "sed: -e expression #1, char 8: unknown option to `s'". So simply changing it to sed "s:~.*:$PWD:" file.txt did the trick. Show Sample Output

xargs -P N spawns up to N worker processes. -n 40 means each grep command gets up to 40 file names each on the command line.

This command uses mutt to send the mail. You must pipe in a body, otherwise mutt will prompt you for some stuff. If you don't have mutt, it should be dead easy to install.

Force make command to create as many compile processes as specified (4 in the example), so that each one goes into one core or CPU and compilation happens in parallel. This reduces the time required to compile a program by up to a half in the case of CPUs with 2 cores, one fourth in the case of quad cores... and so on.

Colorize output of make, gcc/g++ or diff, making it easier to read at a glance. They are not distributed with make, diff or gcc, but are usually available in the repositories.

This one will work a little better, the regular expressions it is not 100% accurate for XML parsing but it will suffice any XML valid document for sure. Show Sample Output

This is more or less the same as 'reset', but with two advantages: the initial LF character makes sure you're starting a new line to the tty driver, the final one is more reliably a line-end as CR is often unset; and second, 'stty sane' is reliable on older UNIX systems, especially Berkeley-based ones.

This works in some situations where 'reset' and the other alternatives don't.

This will mv all your mp3 files in the current directory to $ARTIST/$ALBUM/$NAME.mp3 Make sure not to use sudo - as some weird things can happen if the mp3 file doesn't have id3 tags.

I used this because I needed to sort the content of a bunch of gzipped log files. Replace sort with something else, or simply remove sort to just rezip everything

this will show the names of the deleted directories, and will delete directories that only no files, only empty directories.
