in thread Using Perl on OS X

Thanks for the response, everyone. However, my Terminal is still not displaying "Hello, world!" This is the code to my program:

#!usr/bin/perl
print "Hello, world!\n";

[download]

I'm assuming this is all I need to type, right?

I would type "my_program" or "perl my_program" after "chmod a+x my_program". The latter would cause the Terminal to respond: "my_program: Command not found." The former would just ignore it and ask for a new command without displaying "Hello, World!"

Any thoughts?!?? Thanks.

    Try changing   #!usr/bin/perl to   #!/usr/bin/perl and see what happens then when you type ./my_program

    You're running into a set of problems that are common to first-time Unix users. Things might go quite a bit better for you if you can find someone who is familiar with Unix or OS X, and buy them a beer/coffee/whatever in exchange for an hour tour.

      I 2nd dws's response - the very 1st thing you need to do is find out where Perl is installed. I have no experience on OS X, but, try
          perl -V

      [download]
      at a command prompt - that will print out the @INC array, which tells you the directories that Perl will search for modules.

      Also, on Linux you can do
          which perl

      [download]
      at a command prompt. That will display something like this:
          /usr/bin/perl

      [download]
      and that is what you should include in your #! line at the very top of each perl script. #!/usr/bin/perl -w.

      Once you've got that shebang line right, then if you do
         chmod +x my_program

and then

    ./my_program

it should run - hopefully.

      Again, I have no experience with OS X, so I don't know how much similarity it has to Unix/Linux.

      HTH.

      Or, if you're a book person (which your tale suggests), get a book about it. Oreilly even has a unix for OS X book now.
