DOSKEY is a command for DOS, IBM OS/2,[1] Microsoft Windows,[2] and ReactOS[3] that adds command history, macro functionality, and improved editing features to the command-line interpreters COMMAND.COM
and cmd.exe
.
History
The command was included as a terminate-and-stay-resident program with MS-DOS and PC DOS versions 5 and later,[4] then Windows 9x,[5] and finally Windows 2000[6] and later.
In early 1989, functionality similar to DOSKEY
was introduced with DR-DOS 3.40 with its HISTORY
CONFIG.SYS directive. This enabled a user-configurable console input history buffer and recall as well as pattern search functionality on the console driver level, that is, fully integrated into the operating system and transparent to running applications. In the summer of 1991, DOSKEY
was introduced in MS-DOS/PC DOS 5.0 in order to provide some of the same functionality. DOSKEY
also added a macro expansion facility, though special support was required before applications such as command line processors could take advantage of it. Starting with Novell DOS 7 in 1993, the macro capabilities were provided by an external DOSKEY
command as well. In order to also emulate the DOSKEY
history buffer functionality under DR-DOS, the DR-DOS DOSKEY
worked as a front end to the resident history buffer functionality, which remained part of the kernel.
DOSKEY
has also been included in IBM OS/2 Version 2.0.[7]
In current Windows NT-based operating systems, the DOSKEY
functionality is built into CMD.EXE, although the DOSKEY
command is still used to change its operation.
The DOSKEY
command is not available in FreeDOS, which has such features built into the command interpreter.[8]
Usage
Command switches
DOSKEY allows the use of several command switches:
DOSKEY [/switch ...] [macroname=[text]]
- Шаблон:Mono
- Installs a new copy of DOSKEY.
- Шаблон:Mono[size]
- Sets size of command history buffer to size.
- Шаблон:Mono
- Displays all DOSKEY macros.
- Шаблон:Mono
- Displays all DOSKEY macros for all executables which have DOSKEY macros.
- Шаблон:Mono[executable name]
- Displays all DOSKEY macros for the given executable.
- Шаблон:Mono
- Displays all commands stored in memory.
- Шаблон:Mono
- Specifies that new text typed is inserted in old text.
- Шаблон:Mono
- Specifies that new text overwrites old text.
- Шаблон:Monoexename
- Specifies the executable.
- Шаблон:Monofilename
- Specifies a file of macros to install.
- Шаблон:Mono

Keyboard shortcuts
During a DOSKEY session, the following keyboard shortcuts can be used:
- Шаблон:Keypress and Шаблон:Keypress
- Recall commands
- Шаблон:Keypress
- Clears command line
- Шаблон:Keypress
- Clears command line from the cursor to the beginning of the line.
- Шаблон:Keypress
- Clears command line from the cursor to the end of the line.
- Шаблон:Keypress
- Displays command history
- Шаблон:Keypress
- Clears command history
- Шаблон:Keypress
- Searches command history
- Шаблон:Keypress
- Selects a command by number
- Шаблон:Keypress
- Clears macro definitions
Command macros
DOSKEY implements support for command macros, a simple text-substitution facility which is used somewhat like command line aliases in other environments.
- Шаблон:Mono
- Command separator. Allows multiple commands in a macro.
- Шаблон:Mono–Шаблон:Mono
- Batch parameters. Equivalent to Шаблон:Mono-Шаблон:Mono in batch programs.
- Шаблон:Mono
- Symbol replaced by everything following the macro name on command line.
Alternatives
The absence of a command history in COMMAND.COM
was a serious inconvenience ever since the earliest versions of MS-DOS. Numerous third-party programs have been written to address the issue; many were available long before Microsoft supplied DOSKEY. Some of them, including JP Software's 4DOS and NDOS, also provide additional editing capabilities lacking in DOSKEY, such as filename completion. Some of the better-known DOSKEY alternatives are Jack Gersbach's DOSEDIT
, Chris Dunford's CED
, Sverre Huseby's DOSED
, Ashok Nadkarni's CMDEDIT
, Steven Calwas's ANARKEY
, Eric Tauck's TODDY
, and enhanced DOSKEY written by Paul Houle.
Paul Houle's Enhanced DOSKEY[9] is designed to be an enhanced drop-in replacement for the DOSKEY.COM that ships with MS-DOS and Windows 9x/Windows Me. It also has a smaller disk and memory-resident footprint. The primary added feature is command and file "auto-completion" via the Tab key. Version 2.5, released in 2014, also adds full support for long filenames (LFN).
