The RWX bits are binary flags in most significant order.
Some examples:
RWX = 111 (binary)
RW- = 110 (binary)
The least-significant bit (rightmost) is worth one, the middle is worth
2, the most significant bit is worth four.
Some examples:
RWX = 4 + 2 + 1 = 7 (decimal)
R-X = 4 + 0 + 1 = 6 (decimal)
R-- = 4 + 0 + 0 = 4 (decimal)
Since we're only counting up as far as 7, you can use those numbers
directly as octal. From 0 to 7, octal, hexadecimal, and decimal numbers
are all represented by the same symbols.
As above with RWX=7 and R=4,
u=RWX, g=RWX o=R-- (user, group, others) = 0774 (octal, with a leading
zero to indicate that it is octal)
