The command is available in the operating systems DEC RT-11, OS/8, RSX-11, TOPS-10, TOPS-20, VMS, Digital Research CP/M, MP/M, MetaComCo TRIPOS, Heath Company HDOS, AmigaDOS, DOS, FlexOS, TSL PC-MOS, SpartaDOS X, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows, ReactOS, AROS, and SymbOS.
The <code>type</code> command is supported by Tim Paterson's SCP 86-DOS. On MS-DOS, the command is available in versions 1 and later. DR DOS 6.0 also includes an implementation of the command.
It is also available in the open source MS-DOS emulator DOSBox and the EFI shell.
In Windows PowerShell, ' is a predefined command alias for the Cmdlet which basically serves the same purpose. originated as an internal command in 86-DOS.
The command-syntax and feature set between operating systems and command shell implementations can differ as can be seen in the following examples.
In Digital Equipment Corporation's RT-11, the command accepts up to six input file specifications. Multiple file specifications are separated with commas.
The default filetype is .LST. Wildcards are accepted in place of filenames or filetypes.
The command-syntax on RT-11 is: TYPE[/options] filespecs
TYPE/COPIES:3 REPORT
TYPE/NEWFILES *.LST
In Digital Research CP/M, the command expands tabs and line-feed characters (CTRL-I), assuming tab positions are set at every eighth column.
The command does not support wildcard characters on FlexOS.
The command-syntax on CP/M is: TYPE ufn
Note: ufn = unambiguous file reference
In MP/M, the command has a pause mode. It is specified by entering a 'P' followed by two decimal digits after the filename. The specified number of lines will be displayed and then the command will pause until a carriage return is entered.
The Software Link's PC-MOS includes an implementation of <code>TYPE</code>. Like the rest of the operating system, it is licensed under the GPL v3. It supports an option to display the file content in hexadecimal form.
The command-syntax on PC-MOS is:
.TYPE filename [/h]
The command supports wildcard characters. In Microsoft Windows and OS/2 it includes the filename in the output when typing multiple files.
The command-syntax on Microsoft Windows and ReactOS is:
type [Drive:][Path]FileName
