I have two systems, one running Fedora 8 and the other running Darwin 8.11.1. On both systems, I have edited /etc/sudoers to allow me to run sudo with no password from my user account. On both systems, I run a shell script that runs sudo, and I need the script to run unattended, which means that the sudo can not prompt for a password when the script runs. On the Fedora system, I accomplished this by commenting out the line "Defaults requiretty" in /etc/sudoers. However, on the Darwin system, /etc/sudoers has no such line to comment out, and the man page for sudoers says that the requiretty flag is off by default. Yet, when I run my shell script on the Darwin system, sudo still prompts for a password.

So, can anyone tell me what to do to allow a shell script sudo to run without a password prompt under Darwin? Thank you in advance to all who respond.

Isn't the default to add the "NOPASSWD" arg in the clause allowing users to run apps?

In the /etc/sudoers file on both the Fedora and Darwin systems, I added the line

which allows me to sudo without being asked for a password, since my account is in the wheel group. However, I need to do something more to get the same result when the sudo is in a shell script. Commenting out the line

in /etc/sudoers on the Fedora system worked -- the shell script runs the sudo and doesn't ask for a password -- but I can't figure out what to do on the Mac OS X/Darwin system. Any suggestions would be greatly appreciated.

One more bit of information, for what it's worth.

On Fedora systems, the wheel group is group number 20. On Darwin systems, it's group number 0. Maybe group number 0 is special? Still, when I changed everything in the Darwin systems to group number 20, admins, I was still prompted for a password, so something else is still going on.
