Hi ranjib,

thanks, it does help!

So it would be enough to change the usage line to put -u in front of -M:

- ---snip---
Usage:
 check_disk -w limit -c limit [-W limit] [-K limit] {-p path | -x device}
[-C] [-E] [-e] [-g group ] [-k] [-l] [-M] [-m] [-R path ] [-r path ]
[-t timeout] [-u unit] [-v] [-X type]
- ---pins---

:-D
