I'm halfway there - there's a selection of things I've done (in Perl) that have been enough to interest people. A couple of thing sufficiently complicated that doing it in a shell script is a terrifying prospect. A couple of others that some just didn't really realise was feasible. (XML Parsing some command outputs to drive some automated reporting).
Several have expressed an interest in learning more - not least, because there's at least two scripts I use that whilst not strictly essential, there's a lot of envy of how easy I've made my life. (And then there's one or two scripts that were put in place as workarounds, but the underlying cause isn't going to get fixed any time soon, either).
