updating Fedora 15 to 16 using preupgrade-cli

Ok I recently updated my fedora 15 to fedora 16 on my workstation at home.

the really easy way to do this is with preupgrade

I happen to like the command line so I used

 #yum -y install preupgrade  
 #preupgrade-cli "Fedora 16 (Verne)"  

Answer yes to the question of do you want to do this.

Just reboot when done and it will do the upgrade for you.  If you have issues Fedora has a good document at http://fedoraproject.org/wiki/How_to_use_PreUpgrade that has a lot of trouble shooting tips.

How to extract .tar.gz , .tar.bz2, .tgz, and .tar files on linux at the command line

Ok there are lots of flags you can use to extract these but the easiest way that pretty much works for them all is.

 #tar xvf filename  

this should work for all of them on a modern version of linux.
