Or cheat and use
Code:
sudo tar -jxvf sblim-sfcc-2.0.2.tar.bz2
if you're in the list of sudoers, or
Code:
su -c "tar -jxvf sblim-sfcc-2.0.2.tar.bz2"
if you're not but you know the root password. As a side note, if you're not a sudoer but you know root password, make yourself a sudoer and do away with root password. ^_^
[EDIT]
By "do away with," I mean stop using 'su' or root (except where needed, such as using YaST or Pirut etc...).
