start with
perldoc perl
read all of that....
} # end of autonomous function
will let you peek into the full text - and not merely the POD.

this is actually a second step forward. That you know
they exist - means that all you need to do is resolve
if you wish to write the code that has already been
written or use the modules that exist already.

depends on why you want to read directory blocks to begin with.
If all you are doing is converting a 'find trick' to perl
then doing the legWork of opendir/readdir/closedir - may
not be what you want - but if you all you need to do is
my $dir = 'stuffPlaceSomeWhere';
opendir(DIR_FH, $dir) or die "can not opendir $dir: $!";
my @allfiles = grep { /^\./ && -f "$some_dir/$_" } readdir(DIR_FH);
closedir DIR_FH;
foreach my $file (@allfiles) {
#long hiddeous sequence of dark malevolent evil
}
you came, you peeked, you moved on.... and did not need
to use the 'use File::Find;"

the CPAN is omniscient, but it also is not likely to talk to you.

there are a lot of documents there worth reading, after you
have finished reading the list in
perldoc perl

deciding that we really have to get a life, rather than recode
something we could have just downloaded from the CPAN....
Oh, you meant what 'normal people' usually use it for.
I don't know, I only know codeMonkies....
