In this example, let's inspect the permissions of the authorized_keys
file with the ls
command:
ls -lah ~/.ssh/authorized_keys
-rw------- 1 void void 1.3K Apr 6 1998 /home/void/.ssh/authorized_keys
We see that the current permissions for the file are: -rw-------
, and if we want to know what that translates to in octal form (an easy form to use when setting permissions using the chmod
command), we can inspect the file with stat
:
stat -c "%a %n" ~/.ssh/authorized_keys
600 /home/void/.ssh/authorized_keys
