help! ( run perldoc as root )

| Has any one had problem when running perldoc as root ?
I have some embedded POD at the end of the file 'x.pl'.
When I use my regular account, 'perldoc x.pl' is just fine.
But when I switch to 'root', the same line above gives me
'No documentation found for x.pl'.
I found in the man page the following warning:
Because perldoc does not run properly tainted, and is known
to have security issues, when run as the superuser it will
attempt to drop privileges by setting the effectiveand real IDs
to nobody's or nouser's account, or -2 if unavailable. If it
cannot relinquish its privileges, it will not run.
I don't know if that is relevant.
Thanks a lot,
Nan

It probably is. What are the permissions of x.pl? Can "nouser"
read it?

| Thank you. That is the problem. I checked the file permission, but
forgot to check the permissions on the path.

Yes.
Why on earth would you need to run perldoc as root?

I need to run a perl script as root in order to do some system check.
The script has some embedded documentation in POD and uses pod2usage to
print it out. And it seems pod2usage
uses perldoc underneath.

Looking at its documentation surely doesn't require root priviledges, does
it? su to some other user matching the file and path permissions, without
root execution priviledges, and you should be able to read the documentation.
