How do I measure execution time of a command on the Windows command line?

How to Measure Execution Time of a Command on the Windows Command Line ⏱️💻

You're at the command line, executing a complex command, and you wonder, "How long is this going to take?". This is a common question, and fortunately, there are several ways to measure the execution time of a command on the Windows command line. Let's explore some easy solutions to this problem! 😊

Option 1: Using the timeit Command

Windows command line provides a built-in command called timeit that can measure the execution time of any command you run. Simply prefix your command with timeit and it will display the elapsed time once the command completes.

Here's an example:

timeit my-command

The output will provide you with the precise time taken by your command to execute. It's that simple! ⏳

Option 2: Using the PowerShell cmdlet Measure-Command

If you prefer using PowerShell, you can utilize the Measure-Command cmdlet. This cmdlet calculates the duration of the specified script block.

Here's an example:

Measure-Command { my-command }

Once executed, the output will include detailed information about the time taken by your command. 🚀

Option 3: Manually Calculating Execution Time

In case you prefer a more hands-on approach, you can manually calculate the execution time using batch scripting or PowerShell scripting.

For Batch scripting, you can use the time command to capture the current time before and after executing your command. Subtracting these two times will give you the execution time.

Here's an example:

@echo off
set start=%time%
my-command
set end=%time%

echo Execution Time: %start% - %end%

In PowerShell, you can achieve the same result using the Get-Date cmdlet and calculating the time difference between the start and end times.

Here's an example:

$startTime = Get-Date
my-command
$endTime = Get-Date

$executionTime = $endTime - $startTime
Write-Host "Execution Time: $executionTime"

These manual methods provide more flexibility and can be customized to suit your specific needs. 🛠️
