behavior of "df" under root and regular user

[Thad P Floryan]

All this banter about ``df'' is interesting.  You're probably better off,
though, writing your own (for A/UX) or retrieving a freely-redistributable
or PD one from one of the comp.sources.* archive sites.

Conspicuous by its absence is a reply to my question last week whether A/UX
has passed any version of SVVS (System V Validation Suite).

In light of how "simple" programs I've just ported over break, it would seem
to me that A/UX has NOT passed any SVVS.  Let's just take as a for-instance
the ``df'' program and a shell script I wrote aeons ago that has worked on
EVERY, repeat, every, UNIX box except for A/UX.  The systems I've tested
include my own 3B1's (SysV), HP-UX (various versions), UTS (Amdahl), Sequent,
Motorola, Convergent, etc etc etc

First the shell script:

	ksh 203/206> cat /usr/local/bin/diskfree
	#
	set `df`
	while [ "$1" != "" ]
	do
	    echo "\"$2 MBytes free = \"; scale=5; ($3 * 512)/1000000" | bc
	    shift;shift;shift;shift;shift;shift
	done
	exit 0
	#
	ksh 203/206> 

Now let's see it run on various systems:

WHY isn't there some white-space between "/users/accent" and "/dev/dsk/c4d0s0"?

Sheesh.


BTW, my A/UX 2.0 stuff arrived today; not bad, one week from date of order.

Also BTW, my Apple Developer's Handbook arrived today, too.  Hmmm, who in their
right mind is gonna pay $25/hour for AppleLink?  That same $25 buys me 2.5
months on PORTAL, NetCom or brt.com (any time of day, any session duration,
any baud up to 19.2K) with full access to the world Usenet community.
