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

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?

Solution 1:

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%

Solution 2:

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
