If you turn it on, program should be a little bit faster. In my test, the program was compiled with no optimization. You’ll probably have to click the Enable experimental console features checkbox first though. And then click Enable new Ctrl key shortcuts. All you have to do to get copy and paste working in Windows 10 is to right-click on the command prompt’s title bar, choose Properties. In cmd, executable files are cached, so consecutive same commands run faster even if full path is not specified. Enabling CTRL C and CTRL V in Windows 10. Result should be 5 ~ 7 ms, and is so close to Measure-Command's estimation: PowerShell> measure-command takes longer if can only be resolved in PATH and your PATH is long (for my laptop it takes 14 ms for a "Hello World" exe at the bottom of PATH). The first mtime measures the running time of the second mtime, which fails fast (and can be considered as a "Hello World" program). Printf("duration: %lld ms\n", unt()) Īssume the utility is mtime. If you do want to include process creation time, just move the line where the start time is recorded. ![]() ![]() To get a closer estimation, you can record start time after the creating subprocess and before waiting for it. In this note i will show how to find paths of executable commands in Windows. In a Windows PowerShell the alternative for the which command is the Get-Command utility. But Measure-Command in PowerShell does not. The where command is a Windows which equivalent in a command-line prompt (CMD). ptime and MSYS2 time) take the process creation time into account. If the value of Command is '-', the command text is read from standard input. The value of Command can be '-', a string. You may consider falling back to cmd /c if can only be interpreted by cmd.exe. Command Executes the specified commands (and any parameters) as though they were typed at the Windows PowerShell command prompt, and then exits, unless NoExit is specified. You want more control of the time program.You can write C code using Windows API to create a utility tool for yourself.
