Application of mkdir command in Linux

The mkdir command is mainly used to create folders in the Linux operating system, and the created folders cannot be renamed. The following small series will introduce you to the usage of the mkdir command in Linux, so that you can understand.

1. Command format:

mkdir [options] directory. . .

2. Command function:

The mkdir command enables you to create a folder or directory named DirName (specified file name) in the specified location. The user who wants to create a folder or directory must have write access to the parent folder of the folder being created. Moreover, the created folder (directory) cannot be the same as the file name in the parent directory (that is, the parent folder), that is, the same directory cannot have the same name (case sensitive).

3. Command parameters:

-m, --mode= mode, set permissions "mode" (similar to chmod) instead of rwxrwxrwx minus umask

-p, --parents can be a path name. At this point, if some directories in the path do not exist yet, with this option, the system will automatically create those directories that do not exist yet, that is, you can create multiple directories at a time;

-v, -- Verbose displays information every time you create a new directory

--help Display this help and exit

--version to output version information and exit
