Is it possible to set an environment variable to the output of a command in cmd.exe

I need to do the equivalent of 

set ENVAR=`some-command`

In a windows/cmd.exe script. Cygwin is not an option.

For bonus marks: Is there some cmd.exe equivalent of backticks in general?

Solution

  • A quick and dirty way would be redirecting it to a file and then reading this, e.g.

    some-command>out.txt
set /p ENVAR=<out.txt

    I think for can also help you, but I don't remember the exact syntax. Try something like

    for /f "usebackq" %x in (`some-command`) do set ENVAR=%x

    I probably forgot some token or delim in the options...
