A Simple Program "Hello World !"

阅读更多

    听说采集数据需要用到perl~于是乎~官网下了个Learning Perl 3rd Edition,研究了下。。发现~e~这语言已经简练的不行了。。。

#!/usr/bin/perl

print "Hello, world!\n"; 

 

 

 

 

#!/usr/bin/perl  #其实~就相当于指了个路径

print "Hello, world!\n";  #唉~这个就不用解释了

    第一次接触perl~没发现什么特别之处,一直听人说perl代码一般不会超过100行,有待实践。。
