Print out environment variable

Question

I created an environment variable as follows:

setx HTTPS_PROXY "website"

And when I try to print it out:

echo %HTTPS_PROXY%
%HTTPS_PROXY%

Answer 1

PetSerAl's comment summarizes the reason from setx /?:

NOTE: 1) SETX writes variables to the master environment in the registry.

      2) On a local system, variables created or modified by this tool
         will be available in future command windows but not in the
         current CMD.exe command window.

Solution: you need to use SET command, e.g. as follows.

set "HTTPS_PROXY=website"
setx HTTPS_PROXY "%HTTPS_PROXY%"

Note that (supposedly complex) website string is typed only once in above code snippet (to avoid a keying mistake) in so far that %HTTPS_PROXY% surely matches data in registry:

reg query hkcu\environment /V HTTPS_PROXY
