Question i wanted to pipe to perl!

thks Freelive.

my initial purpose is wanted to pipe the files to a perl program.

see, say my perl program is getfile.pl (taking file names as argumemnts)
Code:
# getfile.pl
#!/usr/bin/perl -w
 while ($ARGV = shift)
 {
        print "\nprocessing $ARGV...";
        if (-d $ARGV)
        {
           print "\n$ARGV is a DIR\n";
         }
 }

if i use:
> getfile.pl f1 f2 dir1 dir2
to execute the perl file, it's working.

However, if i use:
> ls | getfile.pl OR >find * | getfile.pl
it's not working. It wouldn't recoglise the input argument (@ARGV is empty)

also
>getfile.pl < f1 f2 dir1 dir2

it only recognise f2, dir1, dir2. The first argument f1 is missing. (ie. @ARGV only contains f2, dir1 and dir2)


WHY?

appreciate as usual

NAME
vifm - a ncurses based file manager with vi like keybindings SYNOPSIS
vifm [ options ] [ dir1 [ dir2 ]] DESCRIPTION
This manual page documents briefly the vifm file manager. This manual page was written for the Debian distribution because the original program does not have a manual page. vifm is a ncurses based file manager with vi like keybindings. If you use vi, vifm gives you complete keyboard control over your files without having to learn a new set of commands. For full documentation, visit the doc directory. A better man page may follow later. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. The optional argument dir1 opens an initial directory in the left pane, the dir2 another one for the right pane respectively. If one or both are missing, the current working directory is used. --help Show summary of options. --version Show version of program. SEE ALSO
vi(1), AUTHOR
This manual page was written by Edelhard Becker <becker@edelhard.de>, for the Debian GNU/Linux system (but may be used by others). Edelhard Becker August 27, 2002 VIFM(1)
