Answer 1

你可以试试：

mkdir --parents a/b

Answer 2

mkdir -p a/b/c/d

-p      Create intermediate directories as required.  If this option is not specified, the full path prefix of
         each operand must already exist.  On the other hand, with this option specified, no error will be
         reported if a directory given as an operand already exists.  Intermediate directories are created with
         permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permission
         for the owner.
