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 realize there's a few of these out there, but none exactly in this form, which seems the cleanest to me

Know a better way?

If you can do better, submit your command here.

What others think

Beware of this. If you have this 2 files i.e.

important_file

important file

Your loop will overwrite important_file

I suggest to verify first if the file exists.

for f in *; do file=$(echo $f | tr A-Z a-z | tr ' ' _) [ ! -f $file ] && mv "$f" $file done

I like it :) We don't have rename by default on OS X bash shell. How would I do this if I only wanted to do one file, i.e. without the for loop part?
