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.

This command will show the sum total of memory used in gigabytes by a program that spawns multiple instances of itself. Replace chrome with whatever program's memory usage you are investigating. This command is rather useless on software that only spawns a single instance of itself.
