Simple Disk Usage Command-Line

Here is a command with the flags to give you the bottom-line on your disk usage:

du -chs <somedir>

The key here is "summarize", if you only want the disk usage for each argument.

Where:

-c, --total
    produce a grand total

-h, --human-readable
    print sizes in human readable format (e.g., 1K 234M 2G)

-s, --summarize
    display only a total for each argument
