这可以在一行中完成吗? [英] Can this be done in one line?

问题描述

我像这样提取MAC地址

I am extracting the MAC address like so

my @tmp = split / /, "domain (123.123.123.123) at 00:11:22:33:44:55 [ether] on eth0";
my $vip = $tmp[3];

但是可以不使用临时变量吗?

but can it be done without using a temporary variable?

推荐答案

是的，它可以:

my $vip = (split / /, "domain (123.123.123.123) at 00:11:22:33:44:55 [ether] on eth0")[3];
