Wouldn't this work?
I haven't even run this to check for syntax, so DON'T EVEN trust me! I'm just as clueless as you are
even more so probably, but I would like to know if this is generaly possible && if there are any
downs of using this kind of approach.
print &FilesExt('/tmp','csv','txt')." files renamed\n";
sub FilesExt {
my ($startpath,$orgext,$newext) = @_;
my ($count);
foreach $leaf (glob("$startpath/*")) {
if (-d $leaf) {
$count += FilesExt($leaf,$orgext,$newext);
} elsif ($leaf =~ m/$orgext\z/i) { #case insensitive maybe?
my $oldleaf = $leaf;
$leaf =~ s/$1/$newext/;
rename($oldleaf,$leaf) or warn();
++$count;
}
}
return($count);
}
Comments, monks?
