# here's a cool advanced topic about how to perform conditional logic in ansible without resorting
|
|
# to writing your own module that defines facts. You can do that too, and it's easy to do, but
|
|
# often you just want to run a command and then decide whether to run some steps or not. That's
|
|
# easy to do, and here we'll show you how.
