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.

convert from hexidecimal or octal to decimal

Bash can accept '0x' and '0' notation for hexidecimal and octal numbers, so you just have to output the values.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
hex() { printf "%X\n" $1; }
hex() { bc <<< "obase=16; $1"; }

Python is always such much more readable than most shell scripting.

hex() { echo $1 16op | dc; }

Know a better way?
