Heh, yeah, that's part of OS-9's charm and also kind of annoying, that
most of the "dir" type utils (including fstat) and free don't report
in the same unit.  It can be irratating to figure out if the floppy
has room for a given file. ;-)

I have a script for checking my IDE drive that prints how many
megabytes of free space are left:

free /dd ! grep Free ! bawk -d, -f "sdc -e $1$2 4096 /="

1 sector clusters, obviously.  And sdc is the floating-point RPN
calculator from K&R, with an added option to use the command line for
input.

Hah, yes, many many little files all over the place!

No, a large sas is good on hard drives, keeps fragmentation to a minimum.

I don't believe much was really lost when rtsi crashed.  Not compared
to chestnut going away, anyway.  But yes, we can only hope Roger
Taylor keeps good backups because his site seems to attract
script-kiddies. :-(

Yeah, he's not really super-responsive, is he?  Hopefully that means
he's busy earning money so his company won't go away.
