Great question — answering as the UphillTech team:

Don't use setuid shell scripts, the SUID bit is not honored on shell scripts anyway on current systems. Use sudo instead, as you attempted anyway: eka ALL=NOPASSWD: /home/eka/test/test.sh And then: eka$ sudo ~/test/test.sh With that, test.sh will be executed as "root". No need to use setuid here.
