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.

psg (ps grep) function if you don't have pgrep or don't know how to use it

My variant on this common function. Some highlights:

Allows you to override the default ps args of "aux"

Uses bracket trick to omit the grep process itself without having to use a second grep

Always prints the correct header row of ps output

Limitations: Ugly ps error output if you forget to quote your multi word grep argument

Alternatives

There are 3 alternatives - vote for the best!

What others think

Some systems have similar utilities such as pgrep.

And then... some don't. Is that any reason to downvote a script that is useful to people not blessed with pgrep?
