MKDIR(1) General Commands Manual MKDIR(1)
mkdir – make directories
mkdir [-pv] [-m mode] directory_name ...
The mkdir utility creates the directories named as operands, in the order
specified, using mode rwxrwxrwx (0777) as modified by the current umask(2).
The options are as follows:
Set the file permission bits of the final created directory to the
specified mode. The mode argument can be in any of the formats
specified to the chmod(1) command. If a symbolic mode is
specified, the operation characters “+” and “-” are interpreted
relative to an initial mode of “a=rwx”.
-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.
-v Be verbose when creating directories, listing them as they are
The user must have write permission in the parent directory.
The mkdir utility exits 0 on success, and >0 if an error occurs.
The -v option is non-standard and its use in scripts is not recommended.
The mkdir utility is expected to be IEEE Std 1003.2 (“POSIX.2”) compatible.
A mkdir command appeared in Version 1 AT&T UNIX.
