Perl 程式設計/關鍵字/say

Thesay關鍵字

say類似於print, 但會自動新增換行符。使用真實的FILEHANDLE如FH而不是間接的$fh且沒有LIST會將$_的內容列印到檔案。

要使用此命令，應新增use 5.10。

語法

  say FILEHANDLE LIST
  say FILEHANDLE
  say LIST
  say

示例

程式碼

$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.
