Batch : how to use flagged key parameters in batch script

Question

For my batch script I'm want to know how to use some self defined parameters in my batch script. For example :

MyBatch.bat -env:Test 

or

MyBatch.bat env=Test

I want to know how to parse the value behind the key in my batch script?

Answer 1

To use parameters inside a batch-file, you use variables like %~1 (note the ~ is there to get rid of quotes around a parameter) if you then have a key value pair as parameter, you could do this

@echo off
for /f "tokens=1,2 delims=:=" %%i in ("%~1") do (
  echo %%i %%j
)

Note that = normally counts as a delimiter, causing your batch file to see env=Test as %~1 is env, %~2 is Test. If you want the above solution to work with both, you should use

MyBatch.bat env:Test

and

MyBatch.bat "env=Test"
