Hello students, so first step is to convert an octal equivalent of the binary numbers.
00:18
So whereas the binary number as 100 it is an equivalent to an octal of 4, the binary number of 11100 whereas the binary number of 111 it is an octal of the 7, to the octal 7 and 101 binary number 2 it is an equivalent octal of 5 and 011 it is an equivalent octal of 3 then 010 it is also an equivalent octal of 2.
00:53
So now the second step is to nix owner permission for rx in a binary, so where rx here represents the read and execute permissions are granted to the owner and write the permission is not granted.
01:21
So where in a binary this can be represented as whereas 101 it reads the 1, writes the 0 and executes the 1, so the octal representation of the binary number 101 is 5, so it's an 5 for an octal representation.
01:43
So as the third is for 2 granting, they read, write and execute permission and execute permission to owner to owner no grant permission to other and no grant permissions to other whereas here the binary number as 111000, so the owner for the rwx and with the group of dash and also with the group of dash.
02:38
So the octal of 700 with the owner of 7 and group of 0 and the other of 0.
02:53
So now next is the fourth step is to grant the granting a read, write and execute permission to the owner with no permission it was so with the permission.
03:10
So execute permission for execute permission permission to read and write the permission group owner permission to group to group to group and read the permission other and the read the permission to other to the other.
03:42
So whereas here in a binary 111110100, so here with it has an owner of the r read write execute and a group with the read write nothing and then the with the write only.
04:00
So the octal the octal of 764 as the owner of 7 group of 6 and the other of 4.

Now the next is you to effect of an unmarked on a on a dictionary...
