Disk Usage By User

In shared unix filesystems, like /tmp, it is often useful to find who is using the most disk space.

While

du -sk *

will find large files,

find . -user mc -type f -exec du -k {} \; | awk '{ s = s+$1 } END { print "Total used: ",s }'

will show which user is consuming the most space.

IBM has an article describing this combination of find, du, and awk.
