Why is 777 assned to chmod to permit everything on a file?

chmod 777Thus, 777 (111 111 111) is all permissions for everyone, while 700 (111 000 000) is all permissions only for the owner. Other combinations are also common: 666 (110 110 110) isStart by setting permission numbers to 777 to grant files more access, then use the chmod command to modify specific permissions for each folder in var.
