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.

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

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)

mplayer -vo caca will give you a similar result but in color

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"

ps aux | awk '/name/ {print $2}'

This finds a process id by name, but without the extra grep that you usually see. Remember, awk can grep too!

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.

On other systems, replace 'say' with the name of another text-to-speech engine, e.g. espeak ( http://espeak.sourceforge.net ) or festival ( http://www.cstr.ed.ac.uk/projects/festival )

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

netstat -alnp | grep ::80
