In the FreeBSD world it is common to have a short argument of '-d' for --max-depth. This greatly shortens a command one must type to when a depth argument is used (which from my experience is often).
For example currently to say get the size of all the home directories of users one would use : du /home -h --max-depth=1 . It would make life simpler and make going from FreeBSD systems to Linux systems easier for people and scripts if the syntax : du /home -h -d 1 was also supposed.
