Question

I have to use sudo to run my program:

 sudo ./my_program

I am trying to run git clone from my program, but it tries to use the root user’s SSH keys instead of mine.
Is there a way to execute this single command as the user who originally invoked my program?

I guess I can do:

su - original_user -c "git --version"

But how do I figure out the username of the original user? Or is there another elegant solution this?

Answer 1

The sudo manual shows that $SUDO_USER should give you the original user’s username and $SUDO_UID gives the original user’s UID.
