hello guys!
I have a hash of hashes, for example:
%hash = {
abc => {
def => 1,
},
ghi => {
jkl => 1,
},
};
What happen if I do:
delete($hash{abc}{def});
am I staying with?:
%hash = {
abc => undef,
ghi => {
jkl => 1,
mno => 1,
},
};
That was the first question.
My second one is, I'm looping over the hash and delete keys as shown above if fulfilled a condition. If the ansewer to the first question is yes, is there a short way to delete also the first level key ('abc' in the example) when deleted all second level keys under it. In the example, when performing the above
delete, i would have like to stay with:?:
%hash = {
ghi => {
jkl => 1,
mno => 1,
},
};
Thanks
