Windows 命令提示自定义命令

Question

I am looking for a way to customise some of the Windows command prompt (cmd.exe) commands. I would like the new command to be called instead of the one defined by Windows to do almost the same thing except some minor customisations. An example could be with the pushd command print a message saying which directory is changing to. This could be useful, for example, to have the output a.bat script parsed by another tool.

As an example, pushd.bat would look like:

@echo off
pushd %1
echo Entering directory `%cd%'

...but where should I put this so that it gets called instead of the internal command pushd?

Answer 1

You should not customize internal commands because some of these commands go all the way back to DOS and have hidden bugs and features that some tools might rely on and it is unlikely that you will implement them correctly.

You can add custom aliases with doskey . These are better than batch files. They allow you to add certain mini scripts that help you in your daily command line usage. These can actually override the names of internal commands.

doskey pushd=echo Entering $*^&pushd $*
pushd c:\Windows

You can add your doskey commands to HKCU\Software\Microsoft\Command Processor\AutoRun in the registry but you really need tobe careful if you use it to change existing commands. I recommend that you invent new names for your commands.
