Apart from what GrandFather said, I think you also want to use "chdir", like this: 
my $directory = "/home/e/Doc/AutoMation";

chdir $directory;
opendir( DIR, "." );

for my $file ( readdir DIR ) {
    next unless -f $file;
    open( my $in_fh, '<', $file );
    …
}

Either that, or else you'll need to include the directory name with the file name when you try to do anything with the file: 
opendir( DIR, $directory );
for my $file ( readdir DIR ) {
    next unless -f "$directory/$file";
    open( my $in_fh, '<', "$directory/$file" );
    …
}
