printing keys only using map

Hello everyone,

Can anyone give me a suggestion on lines below:

%hash = map {($_, -M "$dir/$_")} readdir D;
print map "$_\n", sort values %hash;

The thing is this will print the floating point numbers of files recently created/modified. I'd like to print out the file names only while sorting values.

Any help is greatly appreciated,

new bie,

Sorry guys, I just figured it out. The second line should be:

print map "$_\n", (sort {$hash{$_} <=> $hash{$_}}, keys %hash);
