and negative numbers, the left one is the equivalent of multiplying by 2 by 1, and the left shift n is the equivalent of multiplying by 2 of the n-th square4) Calculation process:Example: 3 Convert 3 to binary number 0000 0000 0000 0000 0000 0000 0000 0011, Move the digit high (left) two 0, and the other numbers shift to the left by 2 bits. two vacancies in the low (right) 0. The resulting end result is 0000 0000 0000 0000 0000 0000 0000 1100, converted to decimal is 12.

By default, there are always three files open, standard input (keyboard input), standard output (output to screen), standard error (also output to screen), and their respective file descriptors are 0,1,2. So let's take a look at the differences between the following redirection methods:>/dev/null 2>1In fact, it should be equivalent to this: 1>/dev/null 2

numbers move 2 digits to the left, and finally two vacancies in the low (right) 0. The final result is 0000 0000 0000 0000 0000 0000 0000 1100, The conversion to decimal is 12. >> Operation rules: Move all numbers to the right in binary form, lower down (discard), The vacancy complement sign bit of the high position, that is, positive number 0, negative complement 1.Syntax format:Number of shifts &

">>the arithmetic right shift operator, which represents the right shift with a symbol, uses the highest bit padding to fill the left empty space after the shift. The result of the right shift is: each shift, the first operand is removed by 2, and the number of moves is determined by the second operand.According to the binary form to move all the numbers to the right of the towering digits, low-shifte
