Hello guys, could you briefly explain to me what is the difference between
Code:
[:upper:]*
and
Code:
[[:upper:]]*
wildcards ?

The first is any number of characters from the set ":uper". Because it is not inside a bracket expression, the string "[:upper:]" does not refer to a character class, even though it looks like one.

The second correctly matches zero of more upper-case characters.
