Error PERL Script: No filehandle passed

Stefan Wusowski — Thu, 01 Jul 2004 03:26:38 GMT

Hello,
i want to run slipwire.pl on a HP-UX 11.11 System and i get a error: No filehandle passed at ./slipwire.pl line 157, line 1.

Slipwire.pl is a script to get information about files/directories, create a hash and write this information to a database.

The error is generated by creating the hashes.
..
find($file_list_line);

sub wanted {

$i++;
open (FILEH, $name);

my $key = $name;

$ctx = Digest::SHA1->new;
$ctx->addfile(FILEH);
$sha = $ctx->b64digest;

my @fileinfo;
..

The complete script is attached.

Any ideas???? - Thanks

I might be missing something but I can't see where $name gets set. Possibly therefore, as there is no error checking on the "open()", maybe the "open" fails and FILEH isn't a file handle.

Hello,
$name is set by find ... sub wanted ...

If I commet OUT the create hash lines, the script is running well.

Well, I imagine it does because it's the " $ctx->addfile(FILEH);" that is probably causing the error. I imagine that FILEH is not a valid file handle.

Perhaps you could change the line " open (FILEH, $name);" to

open (FILEH, $name) or die "ERROR: $!\n";

This way you will see if there is an error being generated with the open.

adding

use strict;
use warnings;

at the top of your script might also lead to the problem. I /always/ use those two. It also catches typo's and everyone makes typo's

Enjoy, Have FUN! H.Merijn

Hallo,
thanks.
The error is generate while the open() is try to open a FileHandle for a link and that don't work.
