1).Every 15 minutes between 3:00am and 9:00pm every day
2)Every 2 hour(s) between 6:30:00 AM and 9:30:00 PM.
3)Every hour between 6:30:00 AM and 9:30:00 PM.
4)Runs at 4:30am, noon, and 4 PM.

I have strings like above
I want to get time from those strings like below
1). 15 minutes, 3:00 am , 9:00 pm
2).2 hours, 6:30:00 AM,9:30:00 PM.
3). hour, 6:30:00 AM,9:30:00 PM.
4).4:30am, noon ,4 PM

I have tried using $Time.Split(“”)[4] +" “+ $Time.Split(”")[5] but it did not work because the string is changing in all the formats

So i wanted to find time time in the string.

But no idea.need help on this

To do this you need to use regular expressions. If those are the only string formats you have then I think it’s actually going to be easier to replace the text you don’t want rather than search for the text you’re after - it took me less time to figure out how to do it that way :slight_smile:

Get-Help about_regular_expressions

$strings = 'Every 15 minutes between 3:00am and 9:00pm every day','Every 2 hour(s) between 6:30:00 AM and 9:30:00 PM.','Every hour between 6:30:00 AM and 9:30:00 PM.','Runs at 4:30am, noon, and 4 PM.'

foreach ($string in $strings) {

    $string = ($string -replace "Every|Between|and|day|Runs|at|\.|\,"," ").trim() -replace "\s{2,}",","    

    Write-Output $string
}

I agree with Matt. Removing what you don’t need is sometimes preferable. Otherwise you could be stuck with maintaining this:

$strings = 'Every 15 minutes between 3:00am and 9:00pm every day','Every 2 hour(s) between 6:30:00 AM and 9:30:00 PM.','Every hour between 6:30:00 AM and 9:30:00 PM.','Runs at 4:30am, noon, and 4 PM.'

foreach ($string in $strings) {
    (([regex]::Matches($string, '(\d:?(?:\d{2})?(?::\d{2})?\s?(?:[a|p]m))|\d?\d?\s?(?:hour(?:\(s\))?|minutes?|noon)', @('IgnoreCase'))).Value).Trim()
}
