Mixing Single and Double Quotations in Bash
Alright, I have a script that takes a few arguments, runs data, and then rsyncs the data out to a different server. The problem is that to run the data, I have to take one of the arguments and then run a report using it, which is very bash unfriendly (Ex. [3023.2<>1], [5111.3$]="5", etc).

Run a script at unlock?
Hey, I'd like to get a shell script to run everytime I unlock my computer, on KDE 4. I learned that I could run one by overwriting /usr/lib/kde4/libexec/krunner_lock with a shell script doing its thing, then the original krunner_lock binary, and I'd basically want to do the opposite: launch a script that "undoes" what the locking script ...
