... `$#array` ... gives the index number of the last element in @array. That is (generally) different than `scalar @array` which returns the number of elements in @array. TWIMC: Of historical interest: The single circumstance in which `$#array` will not be different than `scalar @array` (i.e., `@array` evaluated in scalar context) is when the array base `$[` is set to 1. This is no longer possible, and wasn't a good idea when it was possible. See `$[` in Deprecated and removed variables in perlvar for gory details.

I'll post a non-split solution. IRL I'd probably use a regex for this anyway. `my $string = "/alex/samsung/t2"; $string =~ m/(.+)\/(.+)$/; print "$1, $2";` [download] "Age is nothing more than an inaccurate number bestowed upon us at birth as just another means for others to judge and classify us" sulfericacid	[reply] [d/l]

Another regexp if you don't need the path: `my $string = "/alex/samsung/t2"; $string =~ m/([^\/]+)$/; print $1, "\n";` [download]	[reply] [d/l]

Give a man a fish, feed him for a day. Teach a man to fish, feed him for a lifetime. Thanks for providing the detail.	[reply]

Give a man a fish, feed him for a day and fuel his appetite for your fish. Teach a man to fish and you lose your monopoly. :) DWIM is Perl's answer to Gödel	[reply]

I have never understood this 'Give a man a fish' line. It's often used in the context of food aid given by the western world to the starving poor in some distant country. Generally speaking, the native peoples of the world are quite good at extracting fish from rivers, lakes and the sea. I can only assume that they would fish for themselves unless there was a good reason why not. Interestingly, there is a growing awareness that we should be looking back at the agricultural methods of our ancestors and the native peoples in order to feed ourselves in the 21st century without completely trashing the environment. Give a man a fish and he will point out that the sea is full of fish it's just that all of the boats were destroyed in the tsunami. Give a group of men a boat ...	[reply]
