You already know what [ ] do if you've used if-statements before. It's actually an independent thing, if just makes use of it. It returns success when the statement within is true, or error when false.

&& is a short-form if-then. If the thing on the left returns success, run the thing on the right. || is the opposite -- if the thing on the left returns error, run the thing on the right.

Code:
true && echo "This will print"
false && echo "But this won't"

true || echo "This will not print"
false || echo "But this will"
