What distribution is most used in production environment
I've come across Red Hat allot lately and am wondering if I need to get studying. I'm an avid Ubuntu server user but don't want to get stuck only knowing one distro. What is the way to go if i want to know as much as I can for use in real world situations.

Not Linux but there are still a of Unix System V systems out there too. AIX, Solaris and HP-UX. Harder to learn as very much not open source software (although there is the Illumos project with distros like OpenIndiana).
Wow, last time I managed HP-UX, SunOS/Solaris, AIX, and Irix, was last century...
Unfortunately AIX in particular is very much still in use in my industry. Its slowly being phased out but is very much still there.
