In a batch file, how can I get the return value of a command into a variable? For example, I'd like to have a variable set with the 'hostname' return value.

notb,

You can read the output of a command into a variable using the FOR command:

If 'command' returns multiple lines then variable will capture the last line of output. With a little more effort any line can be captured. Let me know what you need.

Note that the hostname of your PC is already in a variable called %computername% and you might not need the FOR command.

DOS IT HELP?

Thanks for the tip on the FOR loop, I didn't know.

As far as the presence of the env var is concerned, wow, that's embarrassing

I'm certainly all set now.
