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.

Empty a file of contents

Ever need to erase the contents of a file and start over from scratch? This easy command allows you to do so. Be warned! This will immediately erase all the contents of your file and start you over from scratch (i.e. your file will be at 0 bytes, like if you touch a file).

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
truncate -s0 file

The downside of output redirection is that you need permissions. So something like

> file

won't play nicely w/ sudo. You'd need to do something like

bash -c '> file'

instead, you could go w/

sudo truncate -s0 file
:> file
> file
> foobar.txt
truncate -s 0 file.txt

Immediately make a file empty. This even works if the file is still being written to. Great for cleaning up huge log files!

Know a better way?

If you can do better, submit your command here.

What others think

I keep forgetting this and using 'echo -n "" > filename' instead.

Duplicate command. Please do search before posting...

Crap! I see that now! The suggested duplicates when you enter the new command never listed these past entries!
