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.

What others think

According to Google translate, it means something like "rename a file that starts with a hyphen". This is a complicated and unsafe way of doing it; if there's another file with the same name deeper down in the directory tree, it will overwrite the first one.

Anyway, a better solution is

mv ./-help help.txt

Or use "--" to signify the end of the flags:

mv -- -help help.txt

(Anything after -- is treated as an argument, not an option)
