I'm asking in this topic 'cause I think most bash experts can be found here;-)
Here we go: can somebody please explain how the 2'nd and 3'rd : are interpreted by bash in following command.
I assume bash uses them as modifiers.
NOTE, this command is dangerous, take care when using.
Anyway, my question is not just a joke, 'cause I'm using scripts like this:
debug=echo # set to : to switch debug off
$debug some command and args
some command and args
