Many commands are the same across many DOS systems, but some differ in command syntax or name.Ī partial list of the most common commands for MS-DOS and IBM PC DOS follows below. The command interpreter preserves the case of whatever parameters are passed to commands, but the command names themselves and file names are case-insensitive. Spaces and symbols such as a "/" or a "-" may be used to allow the command processor to parse the command line into filenames, file specifications, and other options. Additionally, command line switches, or other parameter strings, can be supplied on the command line. Commands that can accept only a single file name are said to accept a filename parameter. In the list below, commands that can accept more than one file name, or a filename including wildcards (* and ?), are said to accept a filespec (file specification) parameter. Copies of these utility command programs had to be on an accessible disk, either on the current drive or on the command path set in the command interpreter. Such utility programs would be stored on disk and loaded just like regular application programs but were distributed with the operating system. If no match is found, an error message is printed, and the command prompt is refreshed.Įxternal commands were too large to keep in the command processor, or were less frequently used. When the user types a line of text at the operating system command prompt, COMMAND.COM will parse the line and attempt to match a command name to a built-in command or to the name of an executable program file or batch file on disk. Some commands are internal-built into COMMAND.COM others are external commands stored on disk.
When an application exits, if the transient portion of the command interpreter in memory was overwritten, DOS will reload it from disk.

The options available with ls are far too numerous to list here, but you can see them all in the online manual ( man) pages.The command interpreter for DOS runs when no application programs are running. You may have multiple options and multiple filenames on a line. Neither the options nor the filename are required (you may use ls by itself to see all the files in a directory). Several options control the way in which the information you get is displayed.This will list the contents of the /etc directory in columns. For example, if you are in your home directory and want to list the contents of the /etc directory, enter: If you would like to list files in another directory, use the ls command along with the path to the directory.You can use * and ? anywhere in the filename fragment. The * represents any number of unknown characters, while ? represents only one unknown character. Lists files that begin with hell followed by one character, such as helli, hello, and hell1.
