`#!/usr/bin/perl --` works for me, but `#!/usr/bin/perl ^M --` doesn't. On what OS does `--` tell the kernel to chop off a character from the path following the `#!`?	[reply] [d/l] [select]

Isn't the point that if the original shebang (on *nix) is: `#!/usr/bin/perl --` [download] And the file gets downloaded to win in binmode it will become: `#!/usr/bin/perl --^M` [download] And the ^M will then be ignored!

'--' isn't used to 'chop off' any characters - when used, as BrowserUk implied earlier, it flags the end of the CLI option list to the script/executable and thus whatever follows (in this case the ^M) is/are arguments to the script/executable. The 'classic' usage is when grep'ping for a string containing dash(es) &/or minus(es) e.g. `grep -- this-string some_file` - which tells grep that 'this-string' is a string and not a malformed CLI option. A user level that continues to overstate my experience :-))	[reply] [d/l]
