To create a folder or directory, you must have the write permission on the parent folder of the created folder. In addition, the created folder (directory) cannot have the same name as the file name in its 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 <模式> (Similar to chmod), rather than rwxrwxrwx minus umask-p, -- parents can be a path name. In this case, if some directories in the path do not exist, after this option is added, the system will automatically create those directories that do not exist, that is, multiple directories can be created at a time;-v, -- verbose displays information every time a new directory is created -- help displays this help information and exits -- version outputs version information and exits www.2cto.com 4. command instance: instance 1: Create an empty directory command: mkdir test1 output: [root @ localhost soft] # cd test [root @ localhost test] # mkdir test1 [root @ localhost test] # ll total 4drwxr-xr-x 2 root 4096 10-25 test1 [root @ localhost test] # www.2cto.com instance 2: recursively create multiple directory commands: mkdir-p test2/test22 output: [root @ localhost test] # mkdir-p test2/test22 [root @ localhost test] # ll total 8drwxr-xr-x 2 root 4096 10-25 test1drwxr-xr-x 3 root 4096 10-25 test2 [root @ localhost test] # cd test2/[root @ localhost test2] # ll total 4drwxr-xr-x 2 root 4096 10-25 test22 [root @ localhost test2] # www.2cto.com instance 3: run the mkdir-m 777 test3 command to create a directory with the permission of 777. the output is as follows: [root @ localhost test] # mkdir-m 777 test3 [root @ localhost test] # ll total 12drwxr-xr-x 2 root 4096 10-25 test1drwxr-xr-x 3 root 4096 10-25 test2drwxrwxrwx 2 root 4096 10-25 test3 [root @ localhost test] # description: test3 permission: rwxrwxrwx instance 4: When a new directory is created, information is displayed.
