Except that the "sh" is unable to execute _any_ standard-UNIX shell script.

heaps of other limitations.)
And except for the fact that the standard utilities sometimes have nonstandard
names, often nonstandard options, and/or produce nonstandard output.
F'r instance:
$ ls any/directory
any/directory
any/directory:
file1
file2
$
We use "head" to format a file header for printing, the Unix" head" is named
"first", so we'll have to rename "tail" to "last" to maintain what MacIDRIS
calls consistency.

You can also get it on floppies, or (last I heard) on CD-ROM; possibly also on
tape.
A/UX 1.1 has a driver for Apple's tape drive, but not for any other tape. This
is a major limitation, especially because a 150-MB cartridge tape costs 50% of
Apple's 40 MB drive, cartridges cost less but have five times the capacity,
and are six times faster. :-(
