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.

You can do some boolean logic like

A or B then C else D using

or : ||

and : &&

So you can do some :

# false || false && echo true || echo false


# true || false && echo true || echo false


# false || true && echo true || echo false


# true || true && echo true || echo false


and so on ...

I use it like :

(ssh example.com 'test something') || $(ssh example.net 'test something') && echo ok || echo ko
function ends_in_y() { case $(date +%A) in *y ) true ;; * ) false ;; esac } ; ends_in_y && echo ok

Functions: date echo false true

The shell has perfectly adequate pattern matching for simple expressions.
