I want to know the status of my running process from the detailed description using REGEX in Windows powershell scripting. I want to extract RUNNING from this string
Name: Process_name Started 2008-04-21 11:33 Status RUNNING Checkpoint Lag 00:00:00

Using -replace
$text = 'Name: Process_name Started 2008-04-21 11:33 Status RUNNING Checkpoint Lag 00:00:00'
$text -replace '.+\sStatus\s(\S+)\sCheckpoint.+','$1'
RUNNING

To extract RUNNING or STOPPED etc. you can try the following:
PS > $s = "Name: Process_name Started 2008-04-21 11:33 Status RUNNING Checkpoint Lag 00:00:00", "Name: Process2_name Started 2008-04-21 11:33 Status STOPPED Checkpoint Lag 00:00:00"
PS > $s | % { if ($_ -match "Status (.+) Checkpoint") {
#Return match from group 1
$Matches[1]
}
}
RUNNING
STOPPED
If you're reading a log-file, you can send the content of it directly to the test like this:
PS > Get-Content mylog.txt | % { if ($_ -match "Status (.+) Checkpoint") {
#Return match from group 1
$Matches[1]
}
}
This is extracting everything between "Status " and " Checkpoint", as long as it's at least 1 character (can be mulitple words also).

Hello Graimer, I got what i was lookin for. But there is something more which i would like to work upon. If in my $s variable is multiline with many instances of status like: "Name: Process_name Started 2008-04-21 11:33 Status RUNNING Checkpoint Lag 00:00:00 Name:Process_name2 Started 2008-04-21 11.34 Status Running Checkpoint Lag 00:00:00" ,how can i get the output as status for both process at same time. like it shud be RUNNING and then again RUNNING. I am very much new to powershell scripting. Please help me out with this. Thank You

Hey. See updated answer. It now takes an array(multiline) and sends one by one through the pipeline (
|) into a foreach loop (%) that looks for status and extracts it in one line at a time.If you're looking for Windows processes, doesn't it make more sense to use Get-Process which supports properties and filtering, or the WMI equivalent, gwmi Win32_Process?
Might be way off the mark here so correct me if I'm mistaken!

The process i am trying to catch is not a windows process. i mean to say that it doesn't create any service or process in task managaer. It just runs in background. So i am not able to catch the status of process using Get-Process.
"Status RUNNING"is part of the string? There appears to be no need to use a regex (unless you want to guard against the case that a process might contain these words in its name, which you would need to specify in your question).
