Could there be a problem with me accessing a file when the script is invoked? What I mean is, when I run the script throught a unix prompt, it works fine. But when an email is sent, and the scripts are envoked, one of the scripts tries to read from a text file which already exists in my directory.

Well, I'm thinking, when an email is sent and the scripts are envoked, they are running under a different context, so I'm thinking that the scripts are running under a different set of permissions. I saw something about setuid, and setgid. How can I use one of these to give certain scripts the permission to read from files that already exist?

Hope what I said made sense.

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com- mand. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
