mkdir - make directories
mkdir [ -m mode ] [ -p ] dir...
SUNWcsu
The mkdir command creates the named directories in mode 777
(possibly altered by the file mode creation mask umask(1)
).
Standard entries
in a directory (for instance, the files ‘.’, for the directory itself, and
‘..’, for its parent) are made automatically. mkdir cannot create these entries
by name. Creation of a directory requires write permission in the parent
directory.
The owner-ID
and group-ID
of the new directories are set to the
process’s effective user-ID
and group-ID
, respectively. mkdir calls the mkdir(2)
system call.
To change the setgid bit on a newly created
directory, you must use chmod g+s or chmod g-s after executing mkdir.
The
setgid bit setting is inherited from the parent directory.
The following
options are supported:
- -m mode
- This option allows users to specify the mode
to be used for new directories. Choices for modes can be found in chmod(1)
.
- -p
- With this option, mkdir creates dir by creating all the non-existing parent
directories first. The mode given to intermediate directories will be the
difference between 777 and the bits set in the file mode creation mask.
The difference, however, must be at least 300 (write and execute permission
for the user).
The following operand is supported:
- dir
- A path name
of a directory to be created.
The following example:
example% mkdir
-p ltr/jd/jan
creates the subdirectory structure ltr/jd/jan.
See
environ(5)
for descriptions of the following environment variables that
affect the execution of mkdir: LC_CTYPE
, LC_MESSAGES
, and NLSPATH
.
The following exit values are returned:
- All the specified directories
were created successfully or the -p option was specified and all the specified
directories now exist.
- >0
- An error occurred.
