Bulk modify read and Write permissions for all files under a file using the Terminal shell command

Before the directory installed on the OpenFire encountered this problem, and today again, you need to modify a folder under all subfolders and files of the three permissions: Read and write to the user, the administrator read and write, all read and write, three must be changed to WR

The process is as follows: For example, I want to modify all the file permissions in the/applications/xampp/xamppfiles/htdocs/folder, then open terminal:

cd/applications/xampp/xamppfiles# #cd到htdocs的父文件夹sudo chmod-r 777 htdocs# #需要管理员权限来递归chmod整个目录, 777 means 3 permission levels are w/r/x Finally keep up with Htdcos, that is, destination folder
