Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

Rsync files with spaces
Using the double dash before the source and target makes the command work fine with weird filenames.

List your largest installed packages (on Debian/Ubuntu)
The other commands were good, but they included packages that were installed and then removed. This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable.

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4948, but shorter, and without the utility function.

kde4 lock screen command
If you wish to launch the kde4 screen saver without the password prompt to exit, use this command: $ qdbus org.freedesktop.ScreenSaver /ScreenSaver org.freedesktop.ScreenSaver.SetActive True Also can be done with: $ /usr/lib/kde4/libexec/kscreenlocker --forcelock

Create iso image of cd/dvd

Find files that are older than x days
Find files that are older than x days in the working directory and list them. This will recurse all the sub-directories inside the working directory. By changing the value for -mtime, you can adjust the time and by replacing the ls command with, say, rm, you can remove those files if you wish to.

Reconstruct standard permissions for directories and files in current directory

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Capture data in ASCII. 1500 bytes
Sniffing traffic on port 80 only the first 1500 bytes
