Commands[edit | edit source]

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.
