Hi Joe,
The command you are looking for is "im triggers" or "im viewtrigger".
Both of these are documented in the Integrity Server Admin CLI guide pdf (for 10.0 and up, I don't remember the name of the pdf for 2009 versions, but the commands have existed for a while)
Basically, im triggers will list out all the triggers you have and you can specify what columns (from the admin client's trigger view) to list out using the --fields parameter, so you might want to use "im triggers --fields=name,rule,scriptParams" to get a list of the names, rules, and parameters of every trigger on your server.
im viewtrigger will give a more detailed look at a specific trigger, for example if you want to see the trigger's references to admin objects or the history of changes to the trigger
