How to establish a remote Gnu screen session that you can re-connect to

Long before tabbed terminals existed, people have been using Gnu screen to open many shells in a single text terminal. Combined with ssh, it gives you the ability to have many open shells with a single remote connection using the above options. If you detach with "Ctrl-a d" or if the ssh session is accidentally terminated, all processes running in your remote shells remain undisturbed, ready for you to reconnect. Other useful screen commands are "Ctrl-a c" (open new shell) and "Ctrl-a a" (alternate between shells). Read this quick reference for more screen commands: http://aperiodic.net/screen/quick_reference

Unix alias for date command that lets you create timestamps in ISO 8601 format

I often need to add a timestamp to a file, but I never seem to remember the exact format string that has to be passed to the date command to get a compact datetime string like 20090220T231410 (i.e yyyymmddThhmmss, the ISO 8601 format popular outside the US)

Instead of writing a multiline if/then/else/fi construct you can do that by one line

instead of writing:

if [[ "$1" == "$2" ]]; then

echo "$1 is equal $2"

else

echo "$1 differs from $2"

fi

do write:

[[ "$1" == "$2" ]] && echo "$1 is equal $2" || echo "$1 differs from $2"

Speak the top 6 lines of your twitter timeline every 5 minutes.....

Pump up the chatter, run this script on a regular basis to listen to your twitter timeline.

This is a rough first cut using several cli clips I have spotted around. There is no facility to not read those things already read to you. This could also easily be put in a loop for timed onslaught from the chatterverse, though I think it might violate several pointsof the Geneva Convention

UPDATE - added a loop, only reads the first 6 twits, and does this every 5 mins.

listen to an offensive fortune

or replace "espeak" with "festival --tts" if you like festival better

when your buddy leaves his computer unlocked use "crontab" or "at" to play at some time that would be most embarassing (during his next sales presentation)

echo "fortune -o | espeak" | at now + 30 minutes

of course you can exclude the "-o" for non offensive fortunes, or if you don't have offensive fortunes installed
