Use the below code to delete multiple files in perl.

Code:
#!/usr/bin/perl

@files = ("file1.txt","file2.txt","file3.txt");
foreach $file (@files) {
    unlink($file);
}

the stat function perldoc -f stat lets you know what the inode change time for a file is so combining the two we get... left as an exercise for the reader

Try the below code, and try to change the parameter 86400 * no of days to make it desire to the requirement.

Code:
my $dir = '/home';
opendir(DIR,$dir) || die "Can't open $dir : $!\n";
my @files = readdir(DIR); 
close(DIR);

foreach my $file(@files)
{
	my $now = time;
	my @stat = stat("$dir/$file");
	if ($stat[9] < ($now - 86400))
	{
		print "Deleting $dir/$file...";
		unlink("$dir/$file");
		print "Done.\n";
	}
}
