Perl初学笔记之Hello World

工作需要开始学Perl,下载个Window版(5.16)的: 下载链接
http://www.activestate.com/activeperl/downloads
安装好了之后，写第一个perl程序

#!/usr/bin/perl 
print "Hello,World!n";

运行结果: (很像Python哦)

c:Perl>perl HelloWorld.pl 
Hello,World!

接着学了下:cpan,虽然不知道这家伙具体是干嘛，应该是能安装各种包，9000多种。
命令如下：看第二次输出的结果，应该是类似于数据库的东东吧。

c:Perl>cpan App::cpanminus 
Set up gcc environment - 3.4.5 (mingw-vista special r3) 
CPAN: Term::ANSIColor loaded ok (v4.02) 
CPAN: Storable loaded ok (v2.34) 
Reading 'C:PerlcpanMetadata' 
Database was generated on Fri, 07 Mar 2014 13:06:13 GMT 
CPAN: Module::CoreList loaded ok (v2.80) 
App::cpanminus is up to date (1.7001). 

然后用cpanm安装模块，命令如下: (cpanm Module::Name)

c:Perl>cpanm YAML 
Set up gcc environment - 3.4.5 (mingw-vista special r3) 
--> Working on YAML 
Fetching http://www.cpan.org/authors/id/I/IN/INGY/YAML-0.90.tar.gz ... OK 
Configuring YAML-0.90 ... OK 
Building and testing YAML-0.90 ... OK 
Successfully installed YAML-0.90 
1 distribution installed 

如果实在不晓得如何用的话: cpanm --help    //-->会看到很多提示。

c:Perl>cpanm --help 
Set up gcc environment - 3.4.5 (mingw-vista special r3) 
Usage: cpanm [options] Module [...] 
 
Options: 
  -v,--verbose              Turns on chatty output 
  -q,--quiet                Turns off the most output 

看上面的安装过程，好像是可以执行cpanm Link,果然是可以:

c:Perl>cpanm http://search.cpan.org/CPAN/authors/id/S/SH/SHARYANTO/Alt-Base-0.0
