Quite right. You can find this information as well as more in shell
programming with the "man bash" command.

Right again. This is a little harder to find, but the "[]" are really
shorthand for the "test" command. So, you can "man test" for more info on how
this works.
I don't mean to sound like I'm saying RTFM, but I know when I was a newbie, it
was very informative to not only know the answer, but know how to find it on
my own. After doing so for a few weeks and perusing above and beyond many
times, I was learning more and more on my own.
