If the string value of the scalar variable that is passed to the subroutine contains special characters, those characters will be used as part of the file path. You do not need to surround the string with single or double quote characters to have those special characters interpreted by the operating system or file system. You will need double-quote characters if you are trying to generate a string value with special characters within the source code of your program as a literal string. > > For me it's strange why after declaration "my $f2 = '/etc/passwd';" paht can > be found but after adding apostrophe like that "$f1 = "'" . $f1 .

That is because the apostrophe characters become part of the path string — not what you want. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
