What does ^& represent in Windows command line?












13














I've noticed the usage of ^& in:



(robocopy c:dirA c:dirB *.*) ^& IF %ERRORLEVEL% LSS 8 SET ERRORLEVEL = 0



I am wondering what does it do?






windows batch cmd.exe

The ^ symbol is the escape character* in Cmd.exe:




Adding the escape character before a command symbol allows it to be treated as ordinary text.

When piping or redirecting any of these characters you should prefix with the escape character: & < > ^ |




Source



However, it has no effect and is actually unnecessary in your command. It appears you want the IF command to be run after the RoboCopy command completes. Therefore you want the & to be parsed as the "command separator" command, which tells Cmd.exe to treat your IF statement as a second command that should be executed after running RoboCopy. As a result, this command is equivalent to the one you're using:



(robocopy c:dirA c:dirB *.*) & IF %ERRORLEVEL% LSS 8 SET ERRORLEVEL = 0



*If ^ is the last character in a command, then it is interpreted as the command continuation character.

    @Biswapriyo That's also true, to use ^ for that purpose it must be the last character in the command.

An IMO inspired problem

Image
14 4 This problem from IMO 1988 is said to be one of the most elegant ones in functional equations. Problem : The function $f$ is defined on the set of all positive integers as follows: begin{align} f(1) = 1, f(3) &= 3, f(2n) = f(n), \ f(4n+1) &= 2f(2n+1) - f(n), \ f(4n+3) &= 3 f(2n+1) - 2f(n) end{align} Find the number of $n$ with $f(n) = n, 1 leq n leq 1988$. The main idea towards the solution is realizing that these conditions stand for the fact that $f(n)$ just reverses the digits in the binary representation of the number $n$. So, essentially the solution is finding the number of binary pallindromes $leq 1988_{10}$. My question is the following : How to reformulate the problem so that $f(n)$ reverses the digits of $n$ in its ternary representation. Or even better, can we reformulate it for a
