Command Reference Guide

This document lists the Command Prompt commands discussed in these articles, along with their arguments and what they do. Arguments contained in square brackets are optional. Several of these commands accept more than three optional arguments, but only up to three are listed.

The roughly equivalent Bash command is also listed in the table, for reference.

Basic File Commands

Command Argument1 Argument2 Argument3 Bash Equivalent Task
cls none none none clear Clear all text from the console
notepad file none none nano Open file for editing, if it exists. If it doesn’t exist, then create it.
type file [file2] [file3] cat Write the contents of a file to stdout. If multiple files are specified, write them all, in order.
copy source target none cp Create an exact copy of source, called target.
move source target none mv Move source to target.
del file [file2] [file3] rm Delete the specified files.
