Perl 编程/关键字/say

Thesay关键字

say类似于print, 但会自动添加换行符。使用真实的FILEHANDLE如FH而不是间接的$fh且没有LIST会将$_的内容打印到文件。

要使用此命令，应添加use 5.10。

语法

  say FILEHANDLE LIST
  say FILEHANDLE
  say LIST
  say

示例

代码

$a = "I am waiting for you! ";
$b = "You are late again. ";
print $a;
print $b;
say $a;
say $b;

返回

I am waiting for you! You are late again. I am waiting for you!
You are late again.
