avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system.

Maybe there's an easier way to set a timeout in the ssh options...

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.

Merge ( directories [looking for improvement]

Using a GUI file managers you can merge directories (cut and paste). This command roughly does the same (it doesn't ask for confirmation (no problem for me) and it doesn't clean up the empty SRC directories (no problem, trivial).

probably does the same:

cp -l SRC TARGET; rm -rf SRC

Split an image in half for use on dual screens (mostly for use under KDE which treats each screen separately)

Output should be two JPG files named like "output-1.jpg" and "output-2.jpg". The convert command is part of ImageMagick so you'll need that and dependent packages installed to use it.

List your largest installed packages (on Debian/Ubuntu)

List packages and their disk usage in decreasing order. This uses the "Installed-Size" from the package metadata. It may differ from the actual used space, because e.g. data files (think of databases) or log files may take additional space.
