-

i've 2 files properties.txt

key1=value1 key2=value2

and template.txt uses file

$key1 xcvsdf sfd $key1 sdf  $key2 lorem $key2 ipsum

i want replace properties properties.txt template.txt , write file. don't want run on python\java runtime since should run on machine without prerequirements

how can using powershell? batch files?

assuming needs able run on powershell 2.0, do:

# read template file $template = get-content .\template.txt  # copy template result variable $result = $template  # loop through list of properties get-content c:\dev\properties.txt |foreach-object{     # split each line key-value pairs     $key,$value = $_ -split '=',2     # replace placeholder appropriate value     $result = $result -replace ('\${0}' -f $key),$value }  # output final result $result |out-file .\result.txt
