Second: you should NOT USE backticks any more, because they are deprecated. If you want what you wrote above write it this way:
Third: hostname -s is an AIX speciality (for "short hostname", that is: without the domain information) and quite dangerous to use. If you are in the habit of copying your resource file to every host you use, then: beware! On Solaris (and HP-Ux, for that matter, perhaps a few other UNIXes too) executing hostname -s as root will result in setting the hostname to "-s", which is hardly what you want. Use this instead:
which will do the same as hostname -s but without the danger of setting the hosts name.
Finally:
You seem to set your environment in your profile (perhaps ~/.profile), which is not the best place to do so. Do it in ~/.kshrc (for the Korn shell, for bash use ~/.bashrc) instead. The difference is that the profile is executed exactly once - when you log in. The resource file is executed every time a new shell instance starts. This way you start every new shell you open, regardless of your session and how much you changed the environment of your current shell, with the same clean and predictable environment.
