startup script as non-root user

[denisl]

I have a startup script linked from /etc/init.d to /etc/rc3.d. When the system boots root starts the script and owns the processes. How can I have the script started as a different user?

Thanks.

man su

When using su I need to pass the script to the su command..

for example..
script1.sh:
su nonroot "script2.sh"

script2.sh
touch nonrootfile

Is there a way I can run script2.sh without calling it from script1.sh? The startup script is a few hundred lines and I don't see how I could pass that to the su command unless I update every line which starts a process with "su nonroot".

I was hoping for a one liner at the top of the script..

A starting point:

#!/bin/ksh
for arg; do args=$args" '$arg'"; done
[ $(id -un) != nonroot ] && exec su nonroot "$0 $args"
# real script here
...

Have you looked at the following construct:

su - nonroot -c "/path/to/script2.sh" > /path/to/logfile 2>&1

We use this to start up Oracle databases (from root at system boot) as user oracle.

I hope that helps.

Hi,

You can use here files

SCRIPT=/some/path/to/file.ksh
su - someuser <<-END
        if [ -f $SCRIPT ]
        then
                . /home/someuser.env
                $SCRIPT
        else
                print "error: $SCRIPT does not exist"
        fi
        exit 0
END
