Get the size of all the directories in current directory (Sorted Human Readable)

This allows the output to be sorted from largest to smallest in human readable format.

Provides numerically sorted human readable du output. I so wish there was just a du flag for this.

du -sch ./*
du -hd 1

OSX's BSD version of the du command uses the -d argument instead of --max-depth.

Know a better way?

If you can do better, submit your command here.

What others think

I've been using a similar compound command for some time, but this approach has the same problem as mine: it invokes du twice, which can be slow in some cases. The only way that I can think of to get around this problem is to get the du totals in the normal numeric form, and then have the command translate the numbers into human-readable form. That seems a shame, since the code to generate human-readable output already exists in du. Maybe the best solution is to submit a patch to give the du command a new switch: sort the output by total size.
