![]() If you turn it on, program should be a little bit faster. In my test, the program was compiled with no optimization. If the value of Command is '-', the command text is read from standard input. The value of Command can be '-', a string. Get better console window with tabs, splits, Quake style, copy+paste, DosBox and PuTTY integration, and much more. In cmd, executable files are cached, so consecutive same commands run faster even if full path is not specified. 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. ConEmu-Maximus5 is a full-featured local terminal for Windows devs, admins and users. 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. If you specify a non-executable file, Start-Process starts the program that is associated with the file, similar to the Invoke-Item cmdlet. To get a closer estimation, you can record start time after the creating subprocess and before waiting for it. But Measure-Command in PowerShell does not. ptime and MSYS2 time) take the process creation time into account. ![]() You may consider falling back to cmd /c if can only be interpreted by cmd.exe. ![]()
