Combining text files into one file

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

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 [email protected] can be filtered with "Matches: DeliveredTo:[email protected]"

Disable annoying sound emanations from the PC speaker
To ensure that it will never come back, you can edit /etc/modprobe.d/blacklist Add "blacklist pcspkr" sans quotes
