NAME

mkdir - make a directory

SYNOPSIS

mkdir [-m mode] [-p] dirname ...

DESCRIPTION

Mkdir creates specified directories in mode 777, taking the file creation mask into account (see umask(2)). Standard entries, `.', for the directory itself, and `..' for its parent, are made automatically.

Mkdir requires write permission in the parent directory.

The following options are accepted:

-m mode

Uses the given mode to create the directory, ignoring the file creation mask. Mode can be given in octal or in symbolic form, as described in chmod(1). The set-group-ID bit is ignored when present in an octal mode.

-p

Creates any missing parent directories. If the -m option is also present, newly created parent directories have the specified mode with /usr/local/heirloom/usr/5bin/mkdir; with /usr/local/heirloom/usr/5bin/s42/mkdir, /usr/local/heirloom/usr/5bin/posix/mkdir, and /usr/local/heirloom/usr/5bin/posix2001/mkdir, the default mode minus umask plus write and execute permission for the invoking user is always applied.

If the set-group-ID bit is set on the parent directory of a newly created directory, it is inherited regardless of the -m option unless explicitly specified as a symbolic mode with `+' or `-'.

DIAGNOSTICS

Mkdir returns exit code 0 if all directories were successfully made. Otherwise it prints a diagnostic and returns nonzero.
