Monks,
I'm running on SunOS 5.10, using perl v5.8.4 .
According to the man page:

Example 3: Executing command with user bin's Environment and Permissions To execute command with the temporary environment and per- missions of user bin, type: example% su - bin -c "command args"
and I run the cmd (from root)
su - myuser -c "/home/myuser/t1.pl"
on file
#!/usr/bin/perl -w use strict; open(OUT,">su-test.log") or die; print OUT "user $ENV{'USER'}\n"; close(OUT) or die; exit;
but get error

Use of uninitialized value in concatenation (.) or string at /home/myuser/t1.pl line 5.

Any ideas, ie why doesn't it work as per man page?

Cheers
Chris
