The body of the script always begins
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?
Hi Ray,
That's what I want, yes. Was just hoping that, since "/dev/clipboard"
is a constant and I'd be executing the command frequently, I could
somehow avoid having to type into the command line.
Looks as if there's no way to specify it in the shebang line. No
matter; I can just hard-code the 'open' inside the script itself. Or,
for that matter, just invoke 'foo.pl </dev/clipboard' with an alias!
TMTOWTDI, as they say.
(Actually I dropped the whole idea when I decided to have the script
write the filtered results back into the clipboard -- which
necessitated hard-coding the path into the script anyway. Moreover,
the whole thing is so non-portable to begin with, there's no point in
all this effort!)
Thanks,
Chap
