Start dd and show progress every X seconds
Adjust "sleep X" to your needs. *NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while).

Quickly move the cursor to different parts of the command line based on a mark.
Use 'ctrl-@' to set a mark. See the first comment for a better explanation.

Resume an emerge, and keep all object files that are already built
For Gentoo: If you do not use this command, portage will fetch the source again, and rebuild the hole application from the top. This command make portage keep all files that ar allready built

Force an fsck on reboot
Force an fsck on reboot. Useful on a system where / has mounted read-only because of file system issues.

Recursively unrar into dir containing archive
From the cwd, recursively find all rar files, extracting each rar into the directory where it was found, rather than cwd. A nice time saver if you've used wget or similar to mirror something, where each sub dir contains an rar archive. Its likely this can be tuned to work with multi-part archives where all parts use ambiguous .rar extensions but I didn't test this. Perhaps unrar would handle this gracefully anyway?

list block devices
Shows all block devices in a tree with descruptions of what they are.
