Hi Chap,

I've read perldoc perlrun but find it pretty confusing. Things I've
tried unsuccessfully are:
#!/usr/bin/perl /dev/clipboard
#!/usr/bin/perl < /dev/clipboard
#!/usr/bin/perl -- /dev/clipboard
The body of the script always begins
while (defined (my $line = <>)) {
...etc
}
I'm not sure if that is what you want. Suppose these lines are in a
file "foo.pl". Then you want foo.pl to run and for it to read in
/dev/clipboard. In the above, it seems like you want Perl to run
/dev/clipboard instead -- which is perhaps not what you are looking for.
You can avoid opening the file by taking it as STDIN:
foo.pl </dev/clipboard
Isn't that what you want?
Actually, I found your question interesting and not surprisingly, there
is actually a Wikipedia article on it:
http://en.wikipedia.org/wiki/Shebang_(Unix)
Support of this is not limited to Perl, but whether or not the operating
system recognizes it (since the use of #! is not Perl-specific). Based
on what's in this article, it seems like this feature is not
portable...though it doesn't say which systems would support it.
Good luck!
