ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

When I echo this to stdio on my system, $# is always 0; but it's a boottime script and when I echo & save the output, it is always 4. I'm new to bash scripting and this isn't my script; I'm just trying to debug why some stuff isn't working as I expect. I doubt this is the cause but I'm still curious what variable this might refer to.
Also if this is something I could Google, I would appreciate some good keywords to try. Being new to bash I didn't know what to look for, and symbols like $# together don't work.
Yeah, that line basically says "while any arguments were given from command-line, do..."
And just by the way, $1, $2, $3, etc is the specific argument on the command-line, e.g arg1, arg2, arg3, and so on. And $@ is the entire string of arguments, e.g. "arg1 arg2 arg3 arg4" and so on.
