Search big files with long lines
This is a handy way to circumvent the "Maximum line length of 2048 exceeded" grep error. Once you have run the above command (or put it in your .bashrc), files can be searched using: $ lgrep search-string /file/to/search

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

grep processes list avoiding the grep itself
Trick to avoid the form: grep process | grep - v grep

convert a latex source file (.tex) into opendocument (.odt ) format
require the tex4ht package . You can open the file with openoffice , I use it much for correct my spelling and grammar .

List the size (in human readable form) of all sub folders from the current location
Sorted in human readable format.

Display the top ten running processes - sorted by memory usage

Rsync remote data as root using sudo
If your user has sudo on the remote box, you can rsync data as root without needing to login as root. This is very helpful if the remote box does not allow root to login over SSH (which is a common security restriction).

Disable beep sound from your computer
This command will disable the beep sound from the PC speaker.

Remote screenshot
Admittedly, I'd never have thought of this without the earlier examples, but here's one that you can execute from your workstation to just display the image from another, without separately doing a file transfer, etc. By the way, I hear a loud beep coming from the other room, so I guess it's not too stealthy :-D

Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net
