I have a directory "/upload" where files are uploaded and downloaded from the internet.

Here are my file permissions
[root@localhost upload]# ls -al
total 56
drw-rw-rw-   3 wohldad nobody  4096 Aug 24 08:51 .
drwxr-xr-x  26 root    root    4096 Aug 22 00:41 ..
-rw-r--r--   1 nobody  nobody  2318 Aug 24 08:50 1124891436
-rw-r--r--   1 nobody  nobody 14726 Aug 24 08:51 1124891462

[download]
The files I'm opening and downloading are 1124891436 and 1124891462. My web server is running as "nobody" and "nobody" has read and write permissions to the directory and files.

Now when I try to open the file to read it using:
open(DLFILE, "<$file_location/$id") || Error('open', 'file');
@fileholder = <DLFILE>;
close (DLFILE) || Error ('close', 'file');

print "Content-Type:application/x-download\n";
print "Content-Disposition:attachment;filename=@filename[0]\n\n";
print @fileholder


}

sub Error {
 print "Content-type: text/html\n\n";
 print "The server can't $_[0] the $_[1]: $! \n";
 exit;
  }

[download]
I get an "The server can't open the file: Permission denied" error.

When I change the directory permissions to: 676, thus adding execute permissions for "nobody" I can download the file.

I read that "open" only needs read and write permissions on a file, is this true? Or do I also need "execute" permissions on a file to user perl's "open"?

How can I open a file without having to need execute permissions?
