I completely agree with the words above.  Many well intentioned version
checks grow stale and cause problems later.

This would get you started:

public class SvcCheck {
     public static boolean check() {
         java.io.File fi = new java.io.File ("/usr/sbin/svcadm");
         return (fi.exists() && fi.canExecute());
     }

     public static void main(String[] args) {
         if (check()) {
             System.out.println("svcadm is available");
             /* Go off and work with svcadm */
         } else {
             System.out.println("svcadm not found");
         }
     }
}


% javac SvcCheck.java
% uname -r
5.11
% java SvcCheck
svcadm is available

Over on a legacy system:

% uname -r
5.9
% java SvcCheck
svcadm not found

Hope this helps - Tim
