[SOLVED] nohup and user permission

I have an ebuild which creates a user (lets say jimy) and set home dir to a proper dir (/opt/jim), login shell to /bin/nologin, and set the owenership, permission...
The ebuild also makes a init file in which contains
su -s /bin/bash -c "/usr/bin/nohup /opt/jimy/jimy.sh &" jimy
which returns "Permission denied"
I guest that since jimy's login shell is /bin/nologin, this makes him unable to run any command at all including /usr/bin/nohup
What is the correct way of doing this?
Thanks.

The first thing I would suspect would be /opt/jimy/jimy.sh not being executable.

_ph, thanks for replying.
What if /opt/jimy/jimy is 770? or even 777
Any other idea?

Try to detect the exact cause of the problem.

1. Read man pages of su and nohup to make sure they behave like you suppose them to (or that you use them like they're supposed to).
2. Try using same command with something different than jimy.sh, like date etc. - simple, but guaranteed to work.
3. Try to give jimy a temporary shell.
4. Try to leave out nohup.

After these experiments you should get a pretty good picture which part of the equation is causing the problem.

how about making the /opt/jimy/jimy.sh script jim's default shell,
and then

Thank you guys,
It was permission problem like _ph said.
the file jimy.sh must be excutable.
