perl - Where should Perl script point to when put on web server?

Question

I need to perform a scheduled backup of my MySQL database.

My web hosting service can run PHP and Perl scripts at chosen hours, so I've decided I would make a Perl script that would call mysqldump.

But in the first line of the Perl script I should put the location of the perl interpreter like #!/usr/bin/perl in Linux.

I didn't find the perl file in my / directory (I have cgi-bin directory).

What should I put in this path?

Answer 1

不#!/usr/bin/perl适合你吗？您确实需要询问您的服务提供商他们在哪里安装了 perl。但是，您将通过使用获得可移植性

#!/usr/bin/env perl

相反，它将搜索目录PATH以确定 perl 在每个平台上的安装位置。

Answer 2

whereis此外，您可以使用命令找到路径：

whereis perl

/usr/bin/perl如果安装不是自定义的，这通常会产生路径。

#!/usr/bin/perl
