Thanks to all. I'll take a look. Right, I'm trying to add to the default %ENV hash. I have a perl module that I wrote that gets a couple of variables out of it. It works fine under Solaris 10, and RHEL 5. However, RHEL 6 seems to treat the environment slightly differently. The variables that I get from env.sh in the other OS's work fine. However not showing up in RHEL 6. So, the reason for this little bit a kludge. :)
