v. briefly: I found myself administering about 10 machines at work (as a
test). I am no administrator by any standard. Our habit of working is
changing (we no longer have fancy tools to play with. Saving on licences
and what have you).
So we setup some machines to play with and investigate as an alternative
to NT and as a development environment (we are a small embedded company
who is trying to save money and stay alive :-) )
We finally settled (no I won't mention any other OSes) on FreeBSD for
ease of use and installation. i.e. easy to take care of the kernel and
the option to just install the core system and build the rest as we
wish, thus keeping it lean and mean.
I find myself repeating little tasks here and there. We got a lot of
utilities and scripts which we found useful and so we want to learn it,
understand it and modify to suit our needs. Like starting up services
and servers, firewall scripts, network scripts, backups, revision
control scripts and ... etc.

We are investigating Perl and we have downloaded some tutorials, any
recommendation (free for now :-) ).
