Are you really a computer literacy at all? 

DOS was based upon CPM and X86 instructions and the shell part might have some features common to the unix in looks. DOS was not unix based at all.

DOS was more DEC VMS oriented in it's shell.

Unix is C-based from AT&T and the BSD free OS in charge except service fees and tape costs in universities to avoid the expectedlaw suites. But BSD  lost the case in the court  of not paying AT&T taxes. It was forbidden to upgrade for new versions bfore year 2000 of the BSD OS.

Anyway the linux part is better than BSD in the 386 era proved.

If the MMU and the heap walker  in linux can catch up those from DEC experts then  I would say unix is not  a brain damaged OS at all.

Just test the malloc in the unix, then it is so lousy that it's better to do 
one's own page swapping such as Windows OS.
