slr> nor have i, my RH7.1, 7.2 and 7.3 boxes all report:
slr> df -b MB
slr> df: invalid option -- b
That was an upper case -B.
Someone sent me a copy of a df man page, said to be
from Mandrake 8.2, that does indeed document -B MB as
being valid. The relevant part of the man page says:
-B, --block-size=SIZE use SIZE-byte blocks
...
SIZE may be (or may be an integer optionally followed by)
one of following: kB 1000, K 1024, MB 1,000,000, M
1,048,576, and so on for G, T, P, E, Z, Y.
Interesting. And certainly unportable.
