Pywmhdmon monitors the available space on up to four of your filesystems.
Pywmhdmon is a WindowMaker dockapp that displays the available space on
up to four of your filesystems. It also contains a bar showing the current HD activity. It currently only works on system which has a /proc/stat like file. The application is easy to configure, invoke it with --help or see the sample rc-file for more information.
As usual, I didn't find a dockapp that fitted me. And I really like to see the current disk activity since my disks are so quiet that I can't
hear when they work.
