mkdir

The mkdir utility shall create the directories specified by the operands, in the order specified. For each dir operand, the mkdir utility shall perform actions equivalent to the mkdir () function defined in the System Interfaces volume of POSIX.1-2017, called with the following arguments: 1. A pathname naming the missing pathname component, ending with a trailing character, as the path argument Each dir operand that names an existing directory shall be ignored without error. Provide a default value for the internationalization variables that are unset or null. (See XBD Internationalization Variables for the precedence of internationalization variables used to determine the values of locale categories.) If set to a non-empty string value, override the values of all the other internationalization variables. Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error. [XSI) ] ![[Option Start]]( Determine the location of message catalogs for the processing of LC MESSAGES. ![[Option End]]( All the specified directories were created successfully, or the -p option was specified and all the specified directories either already existed or were created successfully. The default file mode for directories is a = rwx (777 on most systems) with selected permissions removed in accordance with the file mode creation mask. For intermediate pathname components created by mkdir , the mode is the default modified by u + wx so that the subdirectories can always be created regardless of the file mode creation mask; if different ultimate permissions are desired for the intermediate directories, they can be changed afterwards with chmod . Note that some of the requested directories may have been created even if an error occurs. The System V -m option was included to control the file mode. The System V -p option was included to create any needed intermediate directories and to complement the functionality provided by rmdir for removing directories in the path prefix as they become empty. Because no error is produced if any path component already exists, the -p option is also useful to ensure that a particular directory exists. SD5-XCU-ERN-56 is applied, aligning the -m option with the IEEE P1003.2b draft standard to clarify an ambiguity.
