Using file::find, how can I make it skip whole directories? For example, when recursing through /home I'd like to have the process skip any directory /home/<dir> whose user id is less than 500.
find(\&offenders, $dir);
sub offenders{
# do not include links
return if (-l);
# owner of file but skip
# if owner is not a user
# (uid < 500)
$uid = (lstat($_))[4];
#return if ($uid < 500);
if ($uid < 500){
print "UID is $uid, skipping $File::Find::dir $_\n";
return;
}
# scan only regular files
if (-f){
$uname = getpwuid $uid;
# gather name of file
$fname = $File::Find::name;
# size of file (kb)
$size = (lstat($_))[7];
$size = int($size/1000);
# keep running total of each
# user's space use
$size{$uname} += $size;
}
}
This code will skip files but not whole directories. What I have done wrong?
