如何升级用户目录中安装的所有perl CPAN模块？
[英]How to upgrade all perl CPAN modules installed in a user directory?
问题描述
I have a user directory with CPAN modules and I want to have a script that will upgrade all of the to their latest release. 
我有一个包含CPAN模块的用户目录，并且我想要一个脚本来将所有升级到其最新版本。
Note: it should be executable by any user not only root. 注意：任何用户都应该可以执行此命令，而不仅仅是root用户。
What is the proper command to do this? 正确的命令是什么？
I know that cpan -r should upgrade CPAN modules but I want to force it to do this only for those installed in this specific directory. 我知道cpan -r应该升级CPAN模块，但是我想强迫它仅对安装在此特定目录中的那些模块执行此操作。
