Check These Out

kill some process (same as others) but parsing to a variable
Kills a process matching program. I suggest using $ pgrep -fl program to avoid over-killings Nice the following: kills all bash process owned by guest $ pkill -9 -f bash -u guest

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"

Check if you need to run LaTeX to update the TOC

Simple Video Surveillance by email
This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail. Some systems support mail -a "References: " so that all video surveillance emails are grouped in a single email thread. To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!) For instance with Gmail, emails sent to me+trash@gmail.com can be filtered with "Matches: DeliveredTo:me+trash@gmail.com"
