如何在 OS X 上运行 Perl 脚本？
I honestly can't find the answer anywhere! Presumably I have to run a command in Terminal but what?
老实说，我在任何地方都找不到答案！大概我必须在终端中运行一个命令，但是什么？
(I know this is a real basic and stupid question)

You can run your Perlscript by invoking the Perlinterpreter and giving your file as input:
您可以Perl通过调用Perl解释器并将文件作为输入来运行脚本：
perl myprogram.pl

The easiest way to run a perl script is with the option:
运行 perl 脚本的最简单方法是使用以下选项：
perl myprogram.pl
However, you may find it more useful to add a shebang line at the top of the perl file.
但是，您可能会发现在 perl 文件顶部添加 shebang 行更有用。
#!/usr/bin/perl
print "Hello World!\n";
In order to executethis script, you need to add execute permissions to your program. Run:
为了执行这个脚本，你需要为你的程序添加执行权限。跑：
chmod +x myprogram.pl
Now, in order to run your script, you can simply type:
现在，为了运行您的脚本，您只需键入：
./myprogram.pl

A good tutorial on Perl in OSX can be found here:
可以在此处找到有关 OSX 中 Perl 的好教程：

A generic documentation on executing Perl code is of course perldoc perlrun.
关于执行 Perl 代码的通用文档当然是perldoc perlrun。
To answer your question directly:
要直接回答您的问题：
You can run a perl script on any Unix system by either having the code evaluated and executed from command line:
通过从命令行评估和执行代码，您可以在任何 Unix 系统上运行 perl 脚本：
perl -e 'print "Hello World\n"';
Or you can save your Perl script to a file (customarily having .plextension, say script1.pland with the first line being #!/usr/bin/perl) and then you can execute it as any Unix program (after setting proper execute permissions)
或者你可以将你的 Perl 脚本保存到一个文件中（通常有.pl扩展名，比如script1.pl第一行是#!/usr/bin/perl），然后你可以像任何 Unix 程序一样执行它（在设置适当的执行权限之后）
/path/to/script/script1.pl
You can also execute a script from a file by running perl interpreter as the command and giving the script as a parameter (in this case execute permissions to the script are not needed):
您还可以通过运行 perl 解释器作为命令并将脚本作为参数从文件中执行脚本（在这种情况下不需要脚本的执行权限）：
perl /path/to/script/script1.pl
