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.

A signal trap that logs when your script was killed and what other processes were running at that time

trap is the bash builtin that allows you to execute commands when the current script receives a particular signal.

Uses $0 for the script name, $$ for the script PID, tee to output to STDOUT as well as a log file and ps to log other running processes.

Know a better way?

If you can do better, submit your command here.

What others think

I like the concept, but maybe a simpler example to show how to use trap? It took me a minute to realize that the submission was one command that takes in a string and a list of signals. Either way, you definitely taught me new, very useful command! Cheers!

Sure thing joem86! I posted it because it was something useful that I needed in this particular form, but a simplified example of trap is surely useful to others.
