Question

I am having a batch file where it has set variable. I would like replace each variable with value.

For ex: My batch file looks like follows

Set Sourcefolder=..\..\Release
Set Variable2=/y /R
Set DestFolder=..\..\Output

XCopy %SourceFolder%\Comp1 %DestFolder%\Comp1 %Variable2%
...
...
..

Likewise it has many lines. I would like to replace the variables with value. For example
instead of %SourceFolder% it should replace with value ( ….\release)

How to achieve this ? batch file or Powershell script are preferrale

Answer 1

This is how I would do it:

$script:variables=@{}
gc .\script.bat | %{ if($_ -match "^Set (.+?)=(.+)"){ $script:variables["$($matches[1])"] = $matches[2]}}

$evaluator ={
$group1 = $args[0].groups[1]
$script:variables["$group1"]
}

gc .\script.bat | %{ [Regex]::Replace($_,"%(.+?)%",$evaluator,[Text.RegularExpressions.RegexOptions]::none) } |
out-file .\script2.bat
