Due to lawyers, the product has been renamed ESIX.  (ENIX is too close to
that variant starting with an "X")

Of course, a very usable and preferable ksh.

Erroneous missing items:

sdb is included and *is* a debugger.  Adb is not included.

mcopy, mdel, mdir, mmd, mrd, mren and mtype will copy, del, make directory, 
remove directory, rename a file and display a file, respectively, on an MS-DOS 
disk under ESIX.  Current versions will not work on the DOS partition of a 
hard disk.  Floppy only.

Use ksh.  Jobs is BSD-ism.  This is System V remember.

See /usr/lib/mv_dir.  Works for me.

What current ESIX is missing (although next rev is schedule for 15 AUG)
is SCSI drive support, multiple serial port support, couple of console
bugs, and a doggy slow floppy driver (no cacheing).

Equivalant set of code from SCO Xenix would price out at $2875!  So $610
looks to be quite a bargain.
