Octal. The octal numeral system is a base 8 numeral system. It uses the numerals 0 through 7. The system is similar to binary (base 2) and hexadecimal (base 16). Octal numerals are written using the letter o before the numeral, for example, o04 or o1242. Octal numbers are also sometimes written with a small 8 to the lower right, as in 1242 8 .
In Unix and Unix-like operating systems, chmod is the command and system call used to change the access permissions and the special mode flags (the setuid, setgid, and sticky flags) of file system objects (files and directories).
In hexadecimal, each digit can be 16 values, not 10. This means the digits have the one's place, the sixteen's place, and the next one is the 256's place. So 1h = 1 decimal, 10h = 16 decimal, and 100h = 256 in decimal. Example values of hexadecimal numbers converted into binary, octal and decimal.
A computer number format is the way that computers and calculators represent numbers. Most computers use a system of binary which is composed of ones and zeros. Other systems in use are the octal (0,1-7) or the hexadecimal (0,1-9,A,B,C,D,E,F) systems. So we can use codes, which the computer understands only, as well as other number systems.
The octal numeral system is the base-8 number system, and uses the digits 0 to 7. That means there are only 8 symbols or digits (0, 1, 2, 3, 4, 5, 6, 7) used to form other numbers. The main advantage of using the octal number system is that it uses fewer digits than the decimal and hexadecimal number system.
