Make Directory (Create folders)
Multiple folders will be created in the order specified, using mode rwx rwx rwx (0777) as modified by the current umask.
Syntax mkdir [-pv] [-m mode] folder... Options -m mode Set the file permission bits of the final created directory to the specified mode. The mode can be in any of the formats specified to the chmod command. If a symbolic mode is specified, the operation characters `+' and `-' are interpreted relative to an initial mode of `a=rwx'. -p Create intermediate folders 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. -v Verbose = list folders as they are created.
The -v option is non-standard and its use in scripts is not recommended.
The user must have write permission in the parent directory.
If an error occurs, mkdir exits with a value >0.
