saving . . .saved-rwxr--r-- 1 has been deleted.-rwxr--r-- 1 has been hidden .
In video ls -l example1, this command gives the result -rwxr--r-- 1. But in my system, when I execute this command, it gives the result -rwxrw-r-- 1. Why? And what is the meaning of this result? What we can know from this result?
