Is there any command that could show me the size of several folders in linux, perhaps ranked from biggest to smallest?

As others said, du is the way to go. But knowing the options to du is essential. Here they are:

du -m --max-depth 1 /foo /bar

This will give you the size in megabytes of the directories contained in /foo and /bar. If you want the output to be sorted, pipe it through the sort utility:

du -m --max-depth 1 /foo /bar | sort -n -k 1

Or you can pass:

du -sm /dir1 /dir2 | sort -nrk 1
#or
du -sm * | sort -nrk 1

The difference between the first and the second is that the sencond will pick all the files and dirs in the current directory and the first just the dirs you passed.

du -s and sort don't really like each other. –  innaM Nov 11 '09 at 13:04
    
I have yet to run into some kind of problem with these lines in any of my commonly used distros: openSUSE, Arch & Ubuntu. I concour that without the -m switch it would just mess the whole thing. =p –  Mereghost Nov 11 '09 at 13:33
    
Oh god! Sorry. I somehow mixed up -s and -h. Please disregard my comment. –  innaM Nov 11 '09 at 13:52
