12.3 `mkdir': Make directories
`mkdir' creates directories with the specified names.  Synopsis:
     mkdir [OPTION]... NAME...
   `mkdir' creates each directory NAME in the order given.  It reports
an error if NAME already exists, unless the `-p' option is given and
NAME is a directory.
   The program accepts the following options.  Also see *note Common
`-m MODE'
     Set the file permission bits of created directories to MODE, which
     uses the same syntax as in `chmod' and uses `a=rwx' (read, write
     and execute allowed for everyone) for the point of the departure.
     *Note File permissions::.
     Normally the directory has the desired file mode bits at the
     moment it is created.  As a GNU extension, MODE may also mention
     special mode bits, but in this case there may be a temporary window
     during which the directory exists but its special mode bits are
     incorrect.  *Note Directory Setuid and Setgid::, for how the
     set-user-ID and set-group-ID bits of directories are inherited
     unless overridden in this way.
     Make any missing parent directories for each argument, setting
     their file permission bits to the umask modified by `u+wx'.  Ignore
     existing parent directories, and do not change their file
     permission bits.
     To set the file permission bits of any newly-created parent
     directories to a value that includes `u+wx', you can set the umask
     before invoking `mkdir'.  For example, if the shell command
     `(umask u=rwx,go=rx; mkdir -p P/Q)' creates the parent `P' it sets
     the parent's permission bits to `u=rwx,go=rx'.  To set a parent's
     special mode bits as well, you can invoke `chmod' after `mkdir'.
     *Note Directory Setuid and Setgid::, for how the set-user-ID and
     set-group-ID bits of newly-created parent directories are
     Print a message for each created directory.  This is most useful
     with `--parents'.
     Set the default SELinux security context to be used for created

   An exit status of zero indicates success, and a nonzero value
indicates failure.
