I have used Windows NT/2K for a number of years and have been happily using Perl in that environment for at least a couple of years. I have made one or two forays into the world of UNIX so that I know how to get about but that's about it. I have booked a training course that is aimed at the system administrator since it covered tasks beyond the basics covered in the beginners course. I have become reasonably proficient in day-to-day tasks through my use of UNIX to run some of the Perl scripts ported from Win32. My objective at the end of the course is to have the skills to administer a server that I can use to develop and run my Perl apps.
I am looking for a book recommendation (or online resource) so that I can prepare for the course by practising key tasks. I will probably end up buying the Solaris Operating Environment System Administrator's Guide as a reference when I am finished with the course unless there are better recommendations.
