@ARGV == 2 || die "usage: $0 INDEX_FILE '.com'\n";
my ( $INDEX_FILE, $com ) = @ARGV;
my $list = "grep 'href=' $INDEX_FILE|" ;
open (my $HAN, "$list" ) || die "Cannot open '$INDEX_FILE' because
+:: $!";
while (<$HAN>) {
chomp $_;
my @array = split (/\//, $_);
if ($array2 =~ /$com/ ){
my $sorted = $array2;
system (sort -u $scalar);
# - doesn't work
#print "$_\n"
for sort { versioncmp($a,$b) } $sorted;
}
}
