Try:

[^\][\t\r]
  • [] - char class
  • ^ - negation of char class.
  • \] - escape ] as ] is a meta char inside a char class
  • [ - need not escape [ as inside [] its not a meta char
  • \t - tab
  • \r - return carriage

#!/usr/bin/perl

use strict; use warnings;

my ($s) = @ARGV;

if ( $s =~ /^[^\r\t\[\]]*\z/ ) {
    print "$s contains no carriage returns, tabs or square brackets\n";
}

[\w]+

Will match any word character (alphanumeric & underscore).

should be: 

[^\t\r\[\]]

or for the whole string:

^[^\t\r\[\]]*$
