Create an alias in Windows XP

Not many people seem to know about it, but you can use the doskey built-in macro tool, the only issue is that it doesn't save. There are many ways to work around this though.

usage:

doskey ls=dir

ls will now do a directory listing just like dir would.

If you want to use arguments with the commands, use this syntax:

doskey d=dir $*

As for the workaround to make them save:

• save all aliases to a file in this format:

doskey ls=dir
doskey ..=cd ..

and place it in one of the directories in your path. Name it something short like a.cmd, so when you open cmd you can type a to load your aliases.

If typing an a and pressing Enter seems too much work, throw this into your AutoHotkey script:

WinWaitActive, C:\WINDOWS\system32\cmd.exe
Send {a}{Enter}

Loading aliases automatically:

You can change all shortcuts to cmd to point to %SystemRoot%\system32\cmd.exe /K C:\path\to\aliases.cmd, replacing C:\path\to\aliases.cmd with the location of your aliases file. If you typically run it from the run box, you can:

• Rename the cmd executable to cmd2.exe for example, and replace it with a script or another executable which launches the above command (I wouldn't really recommend this method as a lot of apps depend on cmd)
• Make a batch script and call it cmda (cmd with aliases) for example. Have it launch the above command and put this batch script somewhere in your path.

It's a simple as:

1. Create a file with aliases, e.g. c:\bin\aliases:

   ls=dir /ONE $*
   cd=cd /d $*
   python=python -ic "" 
   ps=tasklist $*
   kill=taskkill /IM $*
   

2. Create a file with all the stuff you want to run when cmd.exe is started, including loading the aliases with doskey e.g. c:\bin\cmd_autoruns.cmd:

   @echo off
   cls
   color 0A
   doskey /macrofile=c:\bin\aliases
   

3. Create and run once a batch file (e.g. set_cmd_autorun.cmd) which will set the Command Processor Autorun key to our cmd_autoruns.cmd:

   reg add "hkcu\software\microsoft\command processor" /v Autorun /t reg_sz /d c:\bin\cmd_autoruns.cmd
   

As an alternative to set_cmd_autorun.cmd it is also possible to instead create a .reg file like the one below and then merge it with a double click:

REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
"CompletionChar"=dword:00000009
"DefaultColor"=dword:00000000
"EnableExtensions"=dword:00000001
"PathCompletionChar"=dword:00000009
"Autorun"="c:\\bin\\cmd_autoruns.cmd"

My answer is similar to vriolk's

I created a .bat file that contained my macros (e.g. c:\winscripts\autoexec.bat):

@doskey whereis=c:\winscripts\whereis.cmd $*
@doskey ls=dir /b $*
@doskey l=dir /od/p/q/tw $*

and then from a cmd prompt ran "cmd /?" to find the registry key to edit for the cmd autorun:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
  and/or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun

using regedit, add the path for your macro batch file to the AutoRun value (add the AutoRun key if it's not there):

c:\winscripts\autoexec.bat

now whenever you run "cmd" from the Start->Run prompt, this autoexec.bat will also run and create the doskey macros for you.

By the way, whereis.cmd contains this:

@for %%e in (%PATHEXT%) do @for %%i in (%1%%e) do @if NOT "%%~$PATH:i"=="" echo %%~$PATH:i

which searches your PATH variable for the term you provide:

c:>whereis javaw
c:\jdk\bin\javaw.exe
