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.

send Everyone on your machine some love

This works just like write or wall ... cept one thing the sender is anonymous ... if you really want to drive everyone insane replace echo \"The Matrix has you...\" with cat /dev/urandom

nice one to do on April fool's day

WTF?

Comment by AmirWatad 212 weeks and 2 days ago

WTF and

BTW, using 'w -h' (no headers) you can avoid the egrep. And you don't need to use 'sed' to add "tty".

This one has the same (stupid) result as yours but slightly shorter:

w -h | awk '{print "echo \"The Matrix has you...\" >> /dev/tty" $2}' | bash

nice optimization ...

Comment by copremesis 212 weeks and 1 day ago

I guess you've never heard of "wall" ("write all"). Does same thing.

Package "bsdutils" on Ubuntu.
