Fix VirtualBox error

Clear terminal Screen

Probably the quickest / easiest way to clear the screen.

Speaking alarm clock

This ran on a ubuntu box using espeak for speaking text with the bash shell. On a mac you should use 'say'. Also you can change your alarm interval and your snooze interval which are currently 8 hours and 1 minute. I would run this via cron yet it's easier to disable if you run it as a command like this :P

Find out the last times your system was rebooted (for the duration of wtmp).

Print number of mb of free ram

Here we instead show a more real figure for how much free RAM you have when taking into consideration buffers that can be freed if needed. Unix machines leave data in memory but marked it free to overwrite, so using the first line from the "free" command will mostly give you back a reading showing you are almost out of memory, but in fact you are not, as the system can free up memory as soon as it is needed. I just noticed the free command is not on my OpenBSD box.

check open ports without netstat or lsof

concatenate compressed and uncompressed logs

with zcat force option it's even simpler.

Export all Mailman mailing lists Members to separate .txt files

Export all Mailman mailing lists Members to separate .txt files excluding "Mailman" and "Test" or add yours by && $1!="myDontWannaList"

Get mouse location (X,Y coordinates)

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"
