Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

What others think

no neg from me, but it would be nice for the OP to leave a comment when posting a funny one-liner.

.

xset dpms force on|off

is to turn on and off energy-star features

xset s reset

does something with the screen saver

sleep 0.3

might not work in some systems that do not accept anything except whole seconds.

yeah the 0.3 secs gets rounded to 1 sec on some systems.

although meant for amusement, it does show a simple way to switch the display on/off

combine with a system beep (CTRL-G) for extra annoyance ;-)
