The command <o:p></o:p> yum clean packages <o:p></o:p> will delete the cache of packages that yum has downloaded (normally it <o:p></o:p> stores a copy of everything it downloads). The command <o:p></o:p> yum clean all <o:p></o:p> deletes everything yum has deleted, which means it will have to <o:p></o:p> re-download headers next time you do a yum update. <o:p></o:p> <o:p></o:p> You can also clear out stuff in /tmp: the worst you can do is have to <o:p></o:p> log out and in again. <o:p></o:p> <o:p></o:p> If you want to see where disk space has gone, try running <o:p></o:p> du -sm /* 2>/dev/null <o:p></o:p> The output looks like: <o:p></o:p> 8 /bin <o:p></o:p> 31 /boot <o:p></o:p> 1 /dev <o:p></o:p> 66 /etc <o:p></o:p> 1648 /home <o:p></o:p> 402 /lib <o:p></o:p> etc. <o:p></o:p> The numbers are the size in megabytes. Ignore /dev, /proc and /sys: <o:p></o:p> they're virtual filesystems that don't actually appear on disk. /home is <o:p></o:p> your home directory: you should know what everything in there is. <o:p></o:p> <o:p></o:p> Most programs are under /usr. You can take a look in the subdirectories <o:p></o:p> of (say) /var with <o:p></o:p> du -sm /var/* 2>/dev/null <o:p></o:p> <o:p></o:p> Hopefully you'll have installed all your programs from RPM: using <o:p></o:p> anything else is a recipe for confusion at best and an uninstallable <o:p></o:p> program or an unstable system at worst. <o:p></o:p> <o:p></o:p> I'd be wary of deleting programs you don't know about, or think you <o:p></o:p> don't use. You might think, for example, you never use something with a <o:p></o:p> name like 'e2fsprogs'. But you need the programs to check your disks, <o:p></o:p> especially if you get a disk or filesystem error. <o:p></o:p> <o:p></o:p> As it happens, if you try removing e2fsprogs, you'll get error messages <o:p></o:p> telling you hundreds of packages depend on it. This is A Good Thing, and <o:p></o:p> the packaging system working as needed. If you go ahead and remove those <o:p></o:p> packages, on the other hand, you'll get a broken system. <o:p></o:p> <o:p></o:p> So, as I say, don't delete RPMs you don't know about. <o:p></o:p> <o:p></o:p> If you want a list of candidates, I'd start with running <o:p></o:p> rpm -qa --queryformat '%{NAME} %{GROUP}\n' | grep Amusements/ <o:p></o:p> and *some* of the programs from <o:p></o:p> rpm -qa --queryformat '%{NAME} %{GROUP}\n' | grep Applications/Multimedia <o:p></o:p> <o:p></o:p> Take a look at them, work out what the RPMs are (rpm -qi xmms is good <o:p></o:p> for this), and see if you can delete them without taking RPMs you don't <o:p></o:p> know about or do want with you. <o:p></o:p> <o:p></o:p> Meanwhile, for what it's worth, the standard on this list is to trim <o:p></o:p> e-mails down to what's relevant to your reply, and answer underneath. <o:p></o:p> <o:p></o:p> Hope this helps, <o:p></o:p> <o:p></o:p> James. <o:p></o:p> -- <o:p></o:p> E-mail address: james | 'In a serial interface, the data bits move down a <o:p></o:p> @westexe.demon.co.uk | single channel one after the other, like railway <o:p></o:p> | trains.

The kernels I mentioned other thread is standard kernels (Fedora kernels). My question is how can I delete/remove this issues in a safe and correct way. I don't want leave dead files.
