Question

I have a windows cmd.exe script that runs a child process and needs to collect the output from the child to set three variables. The child process does some work, and prints out three values.

How do I code the parent to collect the values printed out by child ?

I can make any amendments to the child process needed to do this, but the parent script must be written as a cmd.exe batch file.

Answer 1

Is it acceptable that child process set environment variables? parent process should be able to pick that up.

child.bat

set VAR1=123
set VAR2=321

parent.bat

echo %VAR1%
echo %VAR2%
call child.bat
echo %VAR1%
echo %VAR2%

You can set environment variable from child program/script whatever language you are using – there are ways to set environment variables from them.
