在linux下，如何改perl的环境变量

export LD_LIBRARY_PATH=变量lib路径:$LD_LIBRARY_PATH

这是更改系统变量的，如果改perl5的变量，则在perl脚本里面 使用 use lib "变量路径"

把脚本放到/usr/lib/cgi-bin/里面. 并且给执行权限.

然后http://localhost/cgi-bin/test.pl

具体路径参数一下/etc/apache2/sites-enabled/里面的路径配置.

连到Unix系统后，输入命令 which perl ,然后回车。

如果装了perl，就能知道在什么路径下安装的,如果显示找不到，就没装。

已经安装：

[host@host]~% which perl

/usr/bin/perl

[host@host]~%

未安装：

[host@host]~% which perl

perl not found

[host@host]~%

显示版本：

[host@host]~% perl -v
