Dear all,
Can anybody explain me the following expression:
[0-9]{1,2} represent a two digit number, but what does the |100 match
And the + behind all that is also a miracle for me
Many thanks in advance...
Robert
Can anybody explain me the following expression:
Code (perl): (dl
)
my $warning = $1 if ($opt_w =~ /([0-9]{1,2}|100)+/);
[0-9]{1,2} represent a two digit number, but what does the |100 match
And the + behind all that is also a miracle for me
Many thanks in advance...
Robert
