这么简单的程序怎么一个OS可以运行，一个不能？

在Windows平台上
F:\>perl -e "print $_ for (@INC);"
D:\Studio\Perl\binD:\Studio\Perl\libD:/Studio/Perl/libD:/Studio/Perl/site/lib.


在Linux平台上
[root@vmrhel-1 cpan]# perl -e "print $_ for (@INC);"
syntax error at -e line 1, near ");"
Execution of -e aborted due to compilation errors.

找到原因了。原来是单双引号的问题！

Linux用单引号可以，Windows用单引号不行。
Linux用双引号不行，Windows用双引号可以。

wrong answer...
in linux $_ will be replace by null ("")..
because start pattern of variable in shell script  is also start with $..
you need to replace $ by \$...that's all..
