Re: Help me with a regex problem
You might consider using Regexp::Common::net. It provides a convenient set of functions for matching IP v4, v6 and mac addresses. https://metacpan.org/pod/Regexp::Common::net On Fri, 25 Oct 2019 at 19:43, John W.

In other words I can't distinguish the difference between these two "types". I know how to write regex to match each line, but don't get the good result with one regex to match both lines. Can you help? Perhaps if you could describe the problem better?

Re: Help me with a regex problem
/(?[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})\s+(?\/.*)/
To avoid the "leaning toothpick" problem, Perl lets use different match
delimiters, so the above is the same as:
m#(?[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})\s+(?/.*)#
I assume you want to capture the IP and the path, right?
if ( $entry =~ m#([\d.]+)\s+(/\S+)# ) {
my ($ip, $path) = ($1, $2);
print "IP $ip asked for path $path\n";

Re: Help me with a regex problem
That is a backslash followed by a forward slash. The backslash tells the
regex parser to treat the next character as a literal character. Useful for
matching periods, question marks, brackets, etc.
A period matches any character once and an asterisk matches the previous
character any number of times. .* basically means match everything.
Apologies if this is formatted incorrectly. Sending from my phone.

my $n = '[0-9]{1,3}';
if ( =~ ( m[ (?:$n\.){3} $n \s+ \S+ ]x )

# match

Re: Help me with a regex problem
For example, this regex
/(?[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})\s+(?\/.*)/
