DESCRIPTION
For each dir, dot_clean recursively merges all ._* files with their cor-
responding native files according to the rules specified with the given
arguments. By default, if there is an attribute on the native file that
is also present in the ._ file, the most recent attribute will be used.
If no operands are given, a usage message is output. If more than one
directory is given, directories are merged in the order in which they are
specified.
This normalizes volume in your mp3 library, but uses mp3gain's "album" mode. This applies a gain change to all files from each directory (which are presumed to be from the same album) - so their volume relative to one another is changed, while the average album volume is normalized. This is done because if one track from an album is quieter or louder than the others, it was probably meant to be that way.
converts RAW files from a Nikon DSLR to jpg for easy viewing etc.
requires ufraw package
tar directory and compress it with showing progress and Disk IO limits. Pipe Viewer can be used to view the progress of the task, Besides, he can limit the disk IO, especially useful for running Servers.

I've tried all of the screen recorders available for Linux and this is easily the best. xvidcap segfaults; VNC is too much hassle. There are alternatives of this command already here that I am just too lazy to reply to. Messing with the frames per second option, -r, 25 seems to be the best. Any lower and the video will look like a flipbook, if it records at all - -r 10 won't - any faster is the same, oddly enough.
Edit: CLF doesn't like my long command to add audio, so here it is in the description.
$ goaddaudio()
${
$if [ $# != 3 ]; then
$ echo 'goaddaudio < audio > < src video > < dst video >'
$ return
$ fi
$
$ f=goaddaudio$RANDOM
$ ffmpeg -i "$2" &> $f
$ d=$( grep Duration $f | awk '{print $2}' | tr -d ',' ) &&
$ rm $f &&
$ ffmpeg -i "$1" -i "$2" -r 25 -ab 192k -ar 44100 -sameq -t $d "$3"
$}
