Convincing co-workers to learn Perl
One method that has brought me some sucess in the initial "kick-start" phases of getting co-workers to use different tools (and languages) is to provide them with a base functionality tool, and tell them to keep modifying it to suit thier needs (ie: a script that does substitution with hard coded variables to substitute, show them which hard coded parts to change for each new file or substitution they want to do). It is my experience that if the tool is useful to them they will start to tweak it, the day they come to your desk and say "Why didn't you just use @ARGV to read the substitution vars from the command line?" is the day you have tham hooked :)
This approach doesn't work for all, it usually works on the more inquisitive, the ones who are apt to think "I can make this easier...there has to be something he was missing".
Disclaimer: the example is exactly that, an example, and should in no way be construed as a good real life scenario suggestion.
