If you want to create several directories with the command
mkdir you use the -p option. But what does the -p stand for? One could assume it stands for “Path”. But no. It stands for “parent”. And the flag is needed to create a parent directory if it is required. If you try to create a parent and a child directory without the p option, you would get an error.
Instead of -p you can also enter -parent. Both options work:
mkdir -p ParentFolder/ChildFolder
mkdir -paren ParentFolder/ChildFolder
