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

Want to know why your load average is so high? Run this command to see what processes are on the run queue. Runnable processes have a status of "R", and commands waiting on I/O have a status of "D".

On some older versions of Linux may require -emo instead of -eo.
