Description:

For instance I need a regular expression to identify only those numbers between 5278 to 5391.

Why use a regular expression?

my $low = 5278; my $hi = 5391; sub inRange { my $n = shift; return( $hi > $n and $n > $low ); }

It's probably best to use numeric comparisons, but if you absolutely need a regexp, you can use

/^5(2(7[89]|[89]\d)|3([0-8]\d|9[01]))$/

$str =~ /^(?:(?:(?:527[8-9])|(?:52[8-9]\d)|(?:53[0-8]\d)|(?:539[0-1])) +)$/

Here is full example ( regex is from there )

Less-than-optimally efficient one-liner:

print 'Yep' if grep {$_ == $Number} 5278..5391;
