Mkdir: Unable to create directory "oldboy": The file already exists

[Root @ oldboy/] # mkdir-p oldboy/test/geng #-p is a recursive directory. If a file exists, it will not be treated as an error. If the file does not exist, create a directory layer by layer.

-V parameter to display the Directory creation process:

[Root @ oldboy/] # mkdir-p oldboy/a/B/c-v #-v parameter indicates the Directory creation process.

Mkdir: You have created the directory "oldboy/a" # first create directory

Mkdir: directory "oldboy/a/B" # create directory B

Mkdir: the directory "oldboy/a/B/c" has been created. # create directory c.

Note: The-p parameter is commonly used to create a directory recursively. If a directory exists, no error occurs. The-v parameter shows the Directory creation process, which is not commonly used, beginners can refer to the Directory creation process to understand how the-p parameter is recursively created.
