I want to use the same .emacs for all three operating systems. On Windows and fedora I have 22.1 or later, on Solaris I have 21.4 because the admins don't like to upgrade software at all, it seems. Anyway, I have a few things I need to do differently on Solaris so I've been trying to determine if I'm running Solaris by checking the value of $HOME (crude, I know, I'd like to hear of a better way). Since I don't know lisp this is not trivial for me. First I did (in scratch): (getenv "HOME")C-j Prints expected string. Then I tried to do a comparison (if (eq (getenv "HOME") "/home/on/solaris") (message "Duh") )C-j but I get the output Nil from that. So I thought that maybe it doens't like the nested getenv call for some reason, so I tried. (setq u (getenv "HOME"))C-j Ok, prints expected result. But then I noticed something that's odd to me who doesn't know lisp, if I do (print u)C-j it prints the home directory twice...so I started to wondering if u contains the string once or twice... When I tried use the variable u in the if statement instead of the nested getenv call the result was Nil once again. anyway, as you can see I'm really confused, I just want to add some if/else-statements to my emacs. if running-under-solaris is true do this else ; assume we are running under winxp or fedora7 do that - Eric
