I have a simple question I am struggling to find answer to.
I want to write next:
"$env:CI_JOB_STAGE = preprocessing" to a file.

I tried with this:

Add-Content -Path test.bat -Value "$env:CI_JOB_STAGE = preprocessing"

What i receive in file is:

 = preprocessing

Thats because I dont have this variable created yet but I want it to be created later when the file will be executed.

What I want to get in the file is:

$env:CI_JOB_STAGE = preprocessing
