WebSep 28, 2012 · Do it "bitwise" like that: #!/bin/bash a="101" b="011" out="" for ( (i=0; i < $ {#a}; i++ )); do out=$ {out}$ ( ($ {a:$i:1} ^ $ {b:$i:1})) done echo $ {a} ^ $ {b} = $out output: 101 ^ 011 = 110 edit: The inputs need to have the same length!

WebBelow are the 6 Bitwise Operators. AND (&): comparison between two bits. Returns 1 if both bits are 1, else 0. OR ( ): compares two bits and returns 1 if the bits are complementary, else 0. XOR (^): EXCLUSIVE-OR, similar to above operators, it compares both bits and returns 1 if any of the bit is 1. Else it gives 0 if both bits are 0 or 1. WebJun 27, 2016 · It is possible to do that in bc: echo 'xor (10,15)' bc -l logic.bc Or in hex: echo 'obase=16;ibase=16; xor (AA,FF)' bc -l logic.bc Using the logic file from here.

Bash allows us to use bitwise operators via expr, let, declare, or arithmetic expansion. All the following examples of bitwise ANDare therefore valid. But, we should be aware that many operators need to be escaped or quoted: Below, we’ll use only the last type of $((…)), which is the most straightforward to … See more Bitwise operators allow simple, fast, and basic operations on the individual bits of the variables involved. They may seem a heritage of the assembly language era. Yet, we still need … See more We can represent the same numerical quantities with different bases, using methods to convert from one base to another. In particular, … See more In this article, we’ve seen how Bash represents numbers by bits and what basic operations we can do on these bits. Knowledge of the basic rules of Boolean algebra is not strictly necessary, but it will undoubtedly help us … See more how did the crusades affect the world
