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.

mmv most likely must be installed, but is very powerfull when you want to move/copy/append/link multiple files by wildcard patterns.

Same thing using bash built-in features instead of a sub-shell.

Know a better way?

If you can do better, submit your command here.

What others think

You don't need to escape the second part; it's not a pattern. In fact, I don't think that'll produce the correct result.

@kaedenn Thank you very much! I had not thought about it.

Comment by Juev 130 weeks and 1 day ago

Did you even try this? :) At least with my version you get a "Final $ should be \$ or $name at (eval 1) line 1, within string".

The replacement shouldn't have any regexy stuff in it except backreferences -- the dot doesn't need escaping (as pointed out by kaedenn) and the dollar doesn't mean anything.

So you want

rename 's/\.txt$/.md/i' *
