Set the mode of created directories to
mode, which may be symbolic as in
chmod(1)
and then uses the default mode as the point of departure.
-p, --parents
Make any missing parent directories for each
directory argument. The mode
for parent directories is set to the umask modified by u+wx.
Ignore arguments corresponding to existing directories.
(Thus, if a directory /a exists, then mkdir /a is an error,
but mkdir -p /a is not.)
--verbose
Print a message for each created directory. This is most useful
with
--parents.
