Using arepack Trying to convert 18,000+ 7z archive files to zip format with atool fails part way through with one particular file. This file is astrof.7z from the Mame 0.153 romset. The following is the output from the command which fails ...

cd ..
rm -r Unpack-7757
arepack: 0: cannot remove - No such file or directory

I collected the commands in a shell script as follows ....


mkdir Unpack-7757
7z x -oUnpack-7757 astrof.7z
cd Unpack-7757
zip -r ../ .
cd ..
rm -r Unpack-7757

And these execute with no error.

I'm not a perl programmer I work with C and TCL, but I had a look at /usr/bin/atool.

The problem is in the unlink_directory subroutine ...

sub unlink_directory($) {
  my ($dir) = @_;
  die "$::basename: internal error 1 - please report this bug\n"
    if ($dir eq '/' || $dir eq $ENV{HOME});
# chmod 0700, $dir || die "$::basename: cannot chmod `".quote($dir)."': $!\n";
  chdir $dir || die "$::basename: ".quote($dir).": cannot change to - $!\n";
  opendir(DIR, $::cur) || die "$::basename: ".quote($dir).": cannot list - $!\n";
  my @files = readdir(DIR);
  foreach my $file (@files) {
    next if $file eq $::cur || $file eq $::up;
    if (-d $file && !-l $file) {
    } else {
      unlink $file || die "$::basename: ".quote($file).": cannot remove - $!\n";
  chdir $::up || die "$::basename: $::up: cannot change to - $!\n";
  rmdir $dir || die "$::basename: ".quote($dir).": cannot remove - $!\n";

Line 1677 reads: unlink $file || die "$::basename: ".quote($file).": cannot remove - $!\n";

if I change the unlink $file to unlink "./$file" then the error goes away. The file which is generating the error is named "0" (without quotes), so perl must has some issue with the statement "unlink 0".

I can't do anymore but this is a workaround for me.
