Lists installed kernels

no need for rpm, no need for piping to another command. also no real fu but lacking in unnecessary complexity and distro specific commands.
This is sample output - yours may be different.

Remove newlines from output

Remove newlines from output. One character shorter than awk /./ filename and doesn't use a superfluous cat. To be fair though, I'm pretty sure fraktil was thinking being able to nuke newlines from any command is much more useful than just from one file.

Pick a random image from a directory (and subdirectories) every thirty minutes and set it as xfce4 wallpaper

Change your wallpaper every thirty minutes (or however long you like, I suppose) to a randomly selected image in a directory and subdirectories. Bear in mind this is not safe to use if anyone else has write access to your image directory.
This is sample output - yours may be different.

Check These Out

remove execute bit only from files. recursively

keep a log of the active windows

This logs the titles of the active windows, thus you can monitor what you have done during which times. (it is not hard to also log the executable name, but then it is gets too long)

List by size all of the directories in a given tree.

Connect to all running screen instances

There was another line that was dependent on having un-named screen sessions. This just wouldn't do. This one works no matter what the name is. A possible improvement would be removing the perl dependence, but that doesn't effect me.

list files recursively by size

List all groups and the user names that were in each group

"cut" the user names from /etc/passwd and then running a loop over them.

Google text-to-speech in mp3 format

same but redirecting to player and putting whaever text line.. works on my ubuntu machine ...

Mount a partition from within a complete disk dump

Suppose you made a backup of your hard disk with dd: dd if=/dev/sda of=/mnt/disk/backup.img This command enables you to mount a partition from inside this image, so you can access your files directly. Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).

add all files not under version control to repository

This should handle whitespaces well and will not get confused if your filenames have "?" in them

The NMAP command you can use scan for the Conficker virus on your LAN
