My *nix world

Download and untar on the fly

Many times I download an archive, extract it somewhere then remove the archive file from the disk (it's just garbage). I have wondered if it's possible to do download and untar on the fly, by one command only:

wget -O - http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.7.3.tar.bz2|tar -xjf -

So what I did was to download the tar.bz2 archive (wget) to the stdout file (-O -) and then, by using the Linux pipe (|), I've redirected the standard output and I've used it like an input (-) for the tar command.

Now, if you think that this article was interesting don't forget to rate it. It shows me that you care and thus I will continue write about these things.
