And what is the point of having this shebang line: `#!/usr/bin/perl -w` [download] or even more: `#!/usr/bin/perl` [download] under Windows? It makes very little sense...	[reply] [d/l] [select]

At least three decent reasons in general: show intent, help other scripts/utilities with file type/content discovery, and portability.	[reply]

IMHO, none of the three reasons above really apply to Windows. Show intent? How does `#!/usr/bin/perl` say anything to a Windows user that has never used Unix or Linux? If you intend to inform the reader that this is a Perl program (hopefully the reader should know), you might as well add a comment: `# This is a Perl program that should be called as follows: # perl blahblah (args)` [download] Probably clearer for a Win user.. help other scripts/utilities with file type/content discovery Under Windows? Portability? Well, not under Windows... And, under Unix/Linux, I can think of at least half a dozen places where the Perl interpreter file might be located. This is not to say that I don't get your points (I upvoted your post), I am just not fully convinced.	[reply] [d/l] [select]

I never use the shebang unless i am in VM. I just copied code as is.	[reply]

Neither do I. Well, under Unix, I most often have at the top something like `#!/usr/bin/perl` [download] but I don't actually use it most of the time. My shell sripts launching my Perl programs usually have a line like this: `perl foo.pl` [download] or perhaps: `sort -someshellsortoptions file.txt \| perl bar.pl` [download] In brief, I am usually calling Perl explicitly. And I usually don't even care about changing file permissions to executable. And on other systems (Windows/Dos, VMS, etc), it also works usually better this way.	[reply] [d/l] [select]
