It returns a TimeSpan object with components like Days, Hours, Minutes, Seconds, Milliseconds, Ticks, as well as total values like `TotalSeconds`.  \nExample:\n\n```powershell\nMeasure-Command { Get-Process }\n```\n\nYou won\u2019t see the command\u2019s output itself (e.g. list of processes) unless you pipe it:\n\n```powershell\nMeasure-Command { Get-ChildItem | Out-Host }\n```\n([thinkpowershell.com](https://thinkpowershell.com/measure-command-test-script-performance/?utm_source=openai))\n\n### 2. `Get-Date` subtraction\n\nFor finer control or including output, you can manually check the time before and after the command runs and subtract:\n\n```powershell\n$start = Get-Date\n# run your command\nGet-ChildItem\n$end = Get-Date\n$duration = $end - $start\nWrite-Host \"Elapsed time: $duration\"\n```\n([byteinthesky.com](https://www.byteinthesky.com/powershell/measure-execution-time-of-powershell-script/?utm_source=openai))\n\n### 3. `.NET Stopwatch`\n\nIf you're scripting and want even more precision or cleaner formatting:\n\n```powershell\n$sw = [System.Diagnostics.Stopwatch]::StartNew()\n# command or script\nGet-AppxPackage\n$sw.Stop()\nWrite-Host \"Elapsed: $($sw.Elapsed.TotalMilliseconds) ms\"\n```\n([byteinthesky.com](https://www.byteinthesky.com/powershell/measure-execution-time-of-powershell-script/?utm_source=openai))\n\n---\n\n## CMD / Batch\n\nCMD doesn't have a built-in equivalent to Linux `time`, but you can fake it using environment variables (for time) and delayed expansion, or use `START /WAIT`. The granularity is usually limited to the system clock (milliseconds might not be very precise).\n\nHere are some patterns:\n\n### A. Using `%TIME%`\n\n```batch\n@echo off\nsetlocal enabledelayedexpansion\n\nset \"start=%TIME%\"\nREM your command here\ndir C:\\Windows\nset \"end=%TIME%\"\necho Start time: %start%\necho End time:   %end%\"\n```\n\nThen you'd need to parse the times and compute differences manually\u2014which can be tricky.  \n([stackoverflow.com](https://stackoverflow.com/questions/52669229/cmd-measure-command-execution-time?utm_source=openai))\n\n### B. Using `START /WAIT`\n\nCMD\u2019s `START` command can launch a program and with `/WAIT` makes you wait until it finishes. Combined with `%TIME%`, you can get before/after. Example:\n\n```batch\n@echo off\nsetlocal enabledelayedexpansion\n\necho !TIME!\nSTART /WAIT \"\" cmd /c \"your-command-here\"\necho !TIME!\n```\nThen parse.\n\n### C. Full solution from StackOverflow\n\nOne suggested \u201csingle command line\u201d version:\n\n```batch\ncmd /V:on /C \"echo !time! & systeminfo & echo !time!\"\n```\n\n- `/V:on` turns on delayed expansion, so `!time!` reflects the actual time at those moments\n- `systeminfo` is an example command\n([stackoverflow.com](https://stackoverflow.com/questions/52669229/cmd-measure-command-execution-time?utm_source=openai))\n\n---\n\n## Comparison to Linux `time`\n\nLinux `time` gives wall-clock time (\u201creal\u201d), plus CPU times (user, system). PowerShell\u2019s `Measure-Command` and Stopwatch just measure wall-clock elapsed time. CMD-based ways are similarly only measuring wall-clock elapsed time.\n\n---\n\nIf you like, I can help you build a reusable alias or small script so you can run something like `time-your-command` in PowerShell or CMD\u2014makes it feel more like Linux. Do you want me to show you that?"
