Hello all…
Im running centos 7 on my server, and I run command: [root@srvr ~]# ls -al ~/.ssh
and get this result: total 12 drwx------ 2 root root 4096 Feb 24 14:36 . dr-xr-x—. 13 root root 4096 Mar 2 03:46 … -rw------- 1 root root 418 Mar 1 13:50 authorized_keys
Can someone explain what is the command function and the result mean?
The result show total 12, I wonder, is my server had 12 SSH key? Because I only insert 1 ssh key from my laptop.
Thank u all…

The first line when using the list option of
ls -lwill show the amount of disk blocks being used. It’s “physical” space on the hard disk, would probably be the simplest answer. You can run the commandinfo coreutils lsto get a very detailed explanation of every option and the output.Your authorized keys is located in the file called, well,
authorized_keysIf you show the content of that file, it’ll tell you all the keys. One key per line. https://help.ubuntu.com/community/SSH/OpenSSH/Keys
