Commands[edit | edit source]
Some typical CP/M utilities:
|Command||DOS, OS/2, Windows||Unix, Unix-like|
|AUTO||AUTOEXEC.BAT||~/.profile or ~/.login or /etc/rc*|
|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.
