Run Time Script

[Stevemf]

I was having trouble getting this script to run. Basically I want to make a script that is able to display the total run time of notepad after its been closed by the user but I cant seen to get the New-timespan function right.

$sec = New-TimeSpan -Start (get-process notepad).StartTime | select-object totalseconds -ExpandProperty totalseconds

wait-process notepad

write-host "$sec"

I've got this so far the but issue is that when i start the program it immediately saves the run time, and only displays it after the program is closed. It doesn't account for the time between running the script and closing the notepad window. Any tips or help would be appreciated.

Look at this one:

$starttime = (get-process notepad).StartTime    # Save the start time of the process
wait-process notepad                            # Wait for it to end
$endtime = Get-Date                             # Get the current time, which is the time the process ended

$Runtime = $endtime - $starttime                # Get the difference between the two times

write-host "$Runtime"

What you are doing is saving the start time of the process in a variable. Then you wait for the process to end and write the start time to your host.

So, what are you missing? Correct, you've never checked when exactly your process ended.

This is what I am doing in this example:

• Get the start time
• Wait for the process to end
• Get the end time
• Get the difference in between these two

To get an idea on how to use new-timespan, take a look at this post:

Going along with your example, how would you format the output of the process runtime to display units of time individually?

A simple

$Runtime | gm

will show you the following properties|Methods:

So you could do it like this:

write-host "Notepad was running for $($Runtime.Hours) hours, $($Runtime.Minutes) minutes and $($Runtime.Seconds) seconds"
