When experimenting with the ls -l command I noticed that in the /dev folder
ls -l was sometimes printing something like this in the first column :
crw-rw----+
What is this "+"? What does it mean? The man page does not give any information about this.
答案1
This + symbol mean that the file has some additional attributes, like ACL
答案2
You can check the ACL access given to the directory_name run getfacl directory_name to understand the access given to the users.
