This command simply outputs 10 files in human readable, that takes most space on your disk in current directory.

ls -1rSA | tail
2009-10-27 15:34:59
User: rbossy
Functions: ls

This will only work on files since ls won't tell the size of a directory contents.

Note that the first switch is the digit one, not the letter ell.

Know a better way?

If you can do better, submit your command here.

What others think

That won't catch files/directories whose names start with a dot. Try something like this instead:

du -s `find . -maxdepth 1 \! -name '.'` | sort -n | tail

Adding -kh switches to du makes the output a bit more meaningful.

For the dot problem, you can also use:

du -sk * .[^.]* | sort -rn | head

WARN: If you use -h the sort has problems because the units differ, and its slower.
