Thanks for the reply. I was able to get the utility I had written
working, eventually (a bad interpretation of the quotactl() man page
was at fault :-).
In case anyone has any use for a commandline utility to set a users
block quota until linuxconf supports this, the source is below. It's
pretty basic; it sets the hard & soft limit to be the same, though
it would be trivial to extend to have seperate soft & hard limits.
Because this is intended to be used from scripts (at least, that
was my reason for writing it), it returns no output if it is
successful. The syntax is:
quotautil <uid> <quota in blocks> <device>
This utility was written on RH Linux 5.1; I'm not sure how
portable it is. It works for me, but YMMV.
Regards,
Nick Silberstein
