Linux ubuntu 对某个用户 开 某个文件夹 写权限

对某个用户 开 某个文件夹 写权限
背景：将B文件夹对同事A开放 写 权限
Give specific user permission to write to a folder using +w notation

You could use setfacl:

setfacl -m u:username:rwx myfolder

This sets permissions for specific users, without changing the ownership of the directory.

递归，对子目录也进行权限设置
If you want to apply it recursively to all the subdirectories: add the -R flag like this:

setfacl -R -m u:username:rwx myfolder

对多个用户进行权限设置

setfacl -m u:user1:rwx,u:user2:rwx,u:user3:rwx directory_name
