Quickly display a string as Qr Code
Takes the first argument (string) and display a Qr code version of that.

List only executables installed by a debian package
Safe for whitespaces in names.

ignore hidden directory in bash completion (e.g. .svn)
add it in ~/.bashrc install bash-completion

Never rewrites a file while copying (or moving)
Allows you to preserve your files when using cp, mv, ln, install or patch. When the target file exists, it will generate a file named XXX.~N~ (N is an auto-incremental number) instead of deleting the target file.

Compress blank lines in VIM
This command will squeeze all consequent blank lines (including those with only space and tab charactes) to one. It will also empty the resulting line (remove the "|s/.*//" part if you don't need that).

Remove security limitations from PDF documents using ghostscript (for Windows)
#4345 also works under windows

Create a tar archive with all files of a certain type found in present dir and subdirs
Note: the tar archive must not exist in order to create it. If exists it will only be updated and no already existent files in present search will still remain in the tar archive. The update option has to be used instead of create because the command tar may be executed more than once depending on the number of arguments that find throws. You can see maximum number of arguments with 'getconf ARG_MAX'

Batch Convert SVG to PNG (in parallel)
Convert some SVG files into PNG using ImageMagick's convert command. Run the conversions in parallel to save time. This is safer than robinro's forkbomb approach :-) xargs runs four processes at a time -P4

make image semi-transparent

Find usb device in realtime
Using this command you can track a moment when usb device was attached.
