Setting multiple environment variables in a shell spawned via windows batch script

Question

I have a batch file that spawns a shell with a modified path with the following command:

cmd /K set PATH=%PATH%;<additional path locations>

I want to set additional environment variables for the spawned shell as well. Is there any way to do that?

Answer 1

You could also combine them into a single line as follows:

set A=foo & B=bar & C=baz

This way, you could avoid having to modify the original script and run it like so:

set A=foo & B=bar & C=baz & c:\path\to\foo.bat

Answer 2

Simply add another variable on a new line using set as shown in your example. You will also want to remove the /K switch from the first line as execution will stop after that line.

set NEWVAR=SOMETHING

will create a new variable called NEWVAR with the value SOMETHING. If you wish to keep the same behavior and keep cmd open with the /K switch just put it at the end.

example:

set PATH=%PATH%;C:\Folder;
set NEWVAR=SOMETHING
echo %NEWVAR%

Answer 3

summing up what others here posted, along with info gleaned from another post, here's what I saved into my internet_proxy_setup.bat file:

cmd /K "set http_proxy=http://proxy.mycorp.com:1234&& set https_proxy=http://proxy.mycorp.com:1235&& echo In HTTPS Proxy Shell&& cd %~dp0"

where the cd %~dp0 just changes the shell to the same directory that the .bat file is stored in
