You can use rewinddir. Given a directory dirA containing fileA to fileE the script below goes through the directory until it reaches and unlinks dirA/fileB then does a rewinddir then shows directory contents again. Note that fileB no longer appears.

use strict;
use warnings;

my $dir = q{dirA};
opendir my $dh, $dir or die qq{opendir: $dir: $!\n};

while ( my $file = readdir $dh )
{
    if ( $file eq q{fileB} )
    {
        print qq{unlinking $dir/$file ... };
        unlink qq{$dir/$file} or die qq{unlink: $dir/$file: $!\n};
        print qq{done\n};
        last;
    }
    else
    {
        print qq{$dir/$file\n};
    }
}

print qq{+++++++++++\n};
rewinddir $dh;

while ( my $file = readdir $dh )
{
    print qq{$dir/$file\n};
}

Here's the output.

dirA/.
dirA/..
dirA/fileA
unlinking dirA/fileB ... done
+++++++++++
dirA/.
dirA/..
dirA/fileA
dirA/fileC
dirA/fileD
dirA/fileE

I hope this is of use.
