if the user you are using present in sudousers list then you can try below inside script_A.sh

sudo -u user script_B.sh

This is where you have to edit your sudoers file under "User privilege specification" section

<<your mainuser>> ALL=(<<user you want to sudo>>:<<user you want to sudo>>) NOPASSWD: ALL

make sure there are no other line below that such as %admin which might override your line :slight_smile:
