The right shift operator (>>) is one type of bitwise operator in the bash script. A bitwise shift operator shifts the bits of a binary number to the right by a specified number of positions. The right shift operation effectively divides the original number by 2 raised to the power of the shift count.
For example, if you have a variable x and you want to right shift its bits by 2 positions, you can use the syntax:
#!/bin/bash
result=$((x >> 2))
This operation will shift the bits of x two positions to the right, resulting in a division of x by 2 raised to the power of 2. The result is stored in the variable result. The right shift operator is commonly used in bitwise operations and numerical optimizations in Bash scripting.
