NOT "!" or " "

[CJason]

How do you specify NOT "!" or " " (blank)? I know I could write these separately, like:

!/\!/ && !/ /

But, I'd like to use the [] capabilities (if that's actually how you would do this). For example, this would MATCH A-Z (as you all probably know):
/[A-Z]/

Can this form be used for NOT? Thanks in advance!!!

my $string = " ";
if($string !~ /[\! ]/) {
  # Isn't a '!' or ' '
} else {
  # Is
}

No need to escape the '!' character in the regexp.

You could also use the pipe symbol as well...i.e.:

my $string = " ";
if($string !~ /!| ) {
  # Isn't a '!' or ' '
} else {
  # Is
}

Sorry for stealing your code, Nebbish, was a bit short of time !

waiterm, you're missing the closing / on the regex. Should be /!| /.
