I want to create the nested folder .aa/.bb in the current user root's home directory. So I use the command mkdir -p "~/.aa/.bb/". But it doesn't work as I expected and it created a folder ~, which I don't know how to enter into. Below is my testing.
root@u2004:~# pwd
/root
root@u2004:~# ls -la
total 28
drwx------ 3 root root 4096 Aug 28 14:46 .
drwxr-xr-x 20 root root 4096 Aug 28 01:22 ..
-rw------- 1 root root 3285 Aug 28 21:56 .bash_history

root@u2004:~# mkdir -p "~/.aa/.bb/"
