Fellow monks,

I'm beginning to write a script to find older files and email the owners asking them to clean them up. Consider this snipped: 

#using File::Find

sub wanted{ #checks for old files
    if (-r && -f){ 
        #get size of file (MB)
        $size=int((lstat($_))[7]/1000000);

        # check the age of file    
        if ($opt{a} < -A && $size > $opt{s}){
            
            #get user id
            $uid = (lstat($_))[4];

[download]

So now I have the uid, file name, file size and the file age. How do I store it? My though was to create a hash whose name is the uid. The keys (name, size, age) would reference an array for file name, size and age. Now I have these questions:

  1. Is is safe to use a variable variable name for the hash (%$uid)? If so what is the correct syntax?
  2. What is the syntax to push the values into the array referenced by the hash?
  3. Would you do it another way?

Thanks for your time.
