Problem in displaying files

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,
I wrote a simple script to display a list of files in a directory:-

opendir(DIR, $dirname); @FILES= readdir(DIR); foreach $FILE (@FILES){ print $FILE."\n"; } closedir DIR;
The files in the directory are f1 f2 and g3. But I'm getting an output as:-
.
..
f1
f2
g3
What are the dots(. and ..) in the beginning,this is becoming a problem when I want to open files from a directory and perform manipulations on them as the . and .. files cannot be opened.

    you can also try this logic :
    while($file = readdir($dh)) { next if $file eq '.'; next if $file eq '..'; }

    I normally use grep for this:

    @files = grep { $_ ne '.' && $_ ne '..' } readdir DIR;
