WebSep 19, 2024 · Bitwise operators act on the binary format of a value. For example, the bit structure for the number 10 is 00001010 (based on 1 byte), and the bit structure for the number 3 is 00000011. When you use a bitwise operator to compare 10 to 3, the individual bits in each byte are compared. Bash allows us to use bitwise operators via expr, let, declare, or arithmetic expansion. All the following examples of bitwise ANDare therefore valid.
