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.

Strace all signals processes based on a name ( The processes already started... ) with bash built-in

Especially for sysadmins when they don't want to waste time to add -p flag on the N processes of a processname.

In the old school, you did ;

pgrep processname

and typing strace -f -p 456 -p 678 -p 974...

You can add -f argument to the function. That way, the function will deal with pgrep to match the command-line.

Example :

processname -f jrockit

easily strace all your apache processes

This one-liner will use strace to attach to all of the currently running apache processes output and piped from the initial "ps auxw" command into some awk.
