I have several different machine architectures and OS (linux 2.4, linux 2.6, solaris, etc.). For each of those, I have several different builds of perl (with threads, without threads, with specific versions of modules, etc.).

I want to have a shell script which will act as a wrapper to choose the right perl version. I know how to figure out the OS and architecture automatically using uname and such. And I will pass special command line arguments to it in order to tell it that I want the threaded perl version or the non-threaded one. Etc.

But I'm getting into trouble.

Let's say the wrapper shell script is at "/usr/local/bin/perl_wrapper". I would really like to do something like this in my perl script:

  #! /usr/local/bin/perl_wrapper
  print "Hello World!\n";

[download]

But that doesn't seem to work, because apparently "#!" needs to be followed by a compiled binary, not a shell script?

Okay, I can accept that. So I tried using "env" instead:

  #! /usr/bin/env /usr/local/bin/perl_wrapper
  print "Hello World!\n";

[download]

Hey, that works! Great. Now let me just add that "-w" perl switch to it....

  #! /usr/bin/env /usr/local/bin/perl_wrapper -w
  print "Hello World!\n";

[download]

Uh-oh! I get this error message:

  /usr/bin/env: /usr/local/bin/perl_wrapper -w: No such file or direct
+ory

[download]

It's like it's trying to find a file called "/usr/local/bin/perl_wrapper -w".

Okay, what do I do now? You can't pass command line arguments when you use /usr/bin/env?

Any help would be appreciated.

Thanks!

--- UPDATE: For some reason, my carriage return characters aren't showing up in the text above? Oy.

--- UPDATE 2: Okay, now it should be formatted better.
