CP/M

Commands

Some typical CP/M utilities:

CP/M commands and counterparts in other operating systems

Command	DOS, OS/2, Windows	Unix, Unix-like
AUTO	AUTOEXEC.BAT	~/.profile or ~/.login or /etc/rc*
PIP	copy	cp
DIR	dir	ls
program	program	program
TYPE file	type file	cat
USER #	CD	cd ?
DDT	debug	name of debugger?

• Note USER doesn't require a password like login does. Also USER could be argued to be something more like changing a directory.
• PIP - The big difference between copy and cp and PIP is that PIP can be executed without parameters, but when doing this, a blank prompt comes up. Also to copy files between user areas, a user would have to know the hexadecimal locations of the file on the drive, however for copying between drives a pip a: b: would work.
