Recall and edit commands at the DOS prompt, and create macros.

      DOSKEY [options] [macroname=[text]]

   macroname   A short name for the macro.

        text   The commands you want to recall.


   /MACROFILE=filename Specify a file of macros to install

   /MACROS            Display all Doskey macros

   /EXENAME=exename   Specify an  executable other than cmd.exe

   /MACROS:exename    Display all Doskey macros for the given executable

   /MACROS:ALL        Display all Doskey macros for all executables

   ALT+F10            Clear macro definitions

   /HISTORY           Display all commands stored in memory.

   /LISTSIZE=size     Set the number of commands to be remembered by the buffer.
                      (Maximum is 2,147,483,647)

   /REINSTALL         Install a new copy of Doskey (clears the buffer).

In normal use the command line is always in overwrite mode, DOSKEY can be used to
change this to Insert, the [insert] key will always toggle from one to the other:

   /INSERT            By default new text you type at the command line
                      will be inserted in old text

   /OVERSTRIKE        By default new text you type at the command line
                      will overwrite old

   /m /m: and /h are abbreviations for /macros /macros: and /history respectively.
   These provide compatibility with old MS-DOS versions of DOSKEY.

You cannot run a Doskey macro from a batch file, when scripting use the full path to the executable or other task you need to run.

In addition to the above, DOSKEY is loaded into memory for every cmd session so you can use Keyboard shortcuts at the command line.

A DOSKEY macro will be effective for all text input during that session, for example when entering text at a SET /P prompt, if the text starts with a macro keyword, then DOSKEY will perform a substitution, just as if you are typing at the command line. [stackoverflow]

The size of the command history can be set from Control Panel, Console or from the properties of any cmd shortcut.

Clear all history with DOSKEY /REINSTALL


Doskey macro files do not support comments, but you can work around this by creating a fake macro called ; and repeatedly assigining your comment text, if you do this, always end with the line ;= to delete the fake macro.

;= here is a comment
;= another comment line

Advanced macro definitions:

   $T     If you put more than one command in a DOSKEY macro, use $T. 
          to separate them. Equivalent to & in a batch file.

   $1-$9  Parameters, equivalent to %1-%9 in a batch file.

   $*     This represents ALL the parameters $1-9

Save and restore macro definitions

By default, DOSKEY macros are only saved for the current session.
A command like:
DOSKEY /macros >%TEMP%\doskey-macros.txt
Will save all the current macro definitions into a text file.

Then to restore all the macros at a later date:
DOSKEY /macrofile=%TEMP%\doskey-macros.txt


A macro to open notepad
DOSKEY note=notepad.exe

A macro to open WordPad
DOSKEY wpad="C:\Program Files\Windows NT\Accessories\wordpad.exe"

A macro called `d' to run dir/w
DOSKEY d=dir/w

A macro to disable the FORMAT command (n.b. Doskey is not really a reliable method for disabling commands, it is easily bypassed by running the full command path/ extension or creating a different macro.)
DOSKEY Format=Echo I've disabled the Format command.

A macro to open a file with WordPad:

C:\> DOSKEY wpad="%ProgramFiles%\Windows NT\Accessories\wordpad.exe" $1
Using the above macro:
C:\> wpad MyTextfile.txt
