How to check permissions of a file in the Linux system

Question

Hi Guys,

I am new in Linux security concepts. I don't know too much about permissions and security. Can anyone tell me how can I check the permissions of a file?

Hi@akhtar,

If you prefer using the command line, you can easily find a file’s permission settings with the ls command, used to list information about files/directories. You can also add the –l option to the command to see the information in the long list format.

$ ls -l passwd
-rw-r--r--. 1 root root 2653 Aug 13 16:36 passwd

Here you can see that the user only has read power to passwd file.
