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.

I don't think I'll need your command, but you can have a +1 for the ${@:2} -- very useful :-)

what is sxh? is this on the default install for RHEL?

Comment by andrewm659 75 weeks ago

sxh is just the name i gave to the function. You can call it whatever you want, it should work on recent versions of RHEL.
