Uncompressing the lazy way

Always forgetting what options you need to pass to tar to decompress a tar.gz or tar.bz2 or some other archiving tool?

Was it  -zxvf  or  -jxvf  ?

For the lazy Sysadmin or the people who just want to get going with their work right away without having to google for the right options or read through the man pages, there is unp

unp (1)              – a shell frontend for uncompressing/unpacking tools

Available in a repo near you.
