    IF - and that is a big IF - your text is formatted as shown all the time, then take a look at the -Context parameter of Select-String. that accepts one or two [int]s for "lines before, lines after". so -Context 3,1 will grab the 3 lines before the matching line AND the 1 line after it. [grin] ///// take a look at Get-Help Select-String -Parameter Context for more info.

With a regular expression with lookarounds you can find the match

(see the regex live with different escaping =` )



With your text in a file .sample.txt, this snippet:



#requires -Version 3.0

[regex]::match((Get-Content .Sample.txt -raw),"(?sm)(?<=^Start`r?`n).*?Good Morning.*?(?=`r?`nEnd)").Value

#                                                      lookbehind /                   lookahead/


returns



hello

Hello world

Good Morning

    The following will get you what you want. First I grabbed the contents of the txt file and put it in the $doc variable.
    Then using powershell's native "text" search feature I look for the string containing "Good Morning" and if that is true then using regex I grab all contents between the start and end text and create a new txt file with those contents. Below is the code.



    $doc = Get-Content C:Scriptstest.txt
    

    
      if(Select-String -InputObject $doc -Pattern "Good Morning" -SimpleMatch){
    
        $contents = [regex]::Match($doc,'(?is)(?<=bd: Startb).*?(?=bd: Endb)')
    
            New-Item -Path C:Scripts -Name newtest.txt -ItemType File -Value $contents
    
      }
    
      Else{
    
         Write-Host "Nothing Found"
    
      }

    • I tried below code. it generates output file but its blank. can we add like command instead of is start end? $doc = Get-Content "C:Usersa154499DesktoptestPS.txt" if(Select-String -InputObject $doc -Pattern "dwsn14626" -SimpleMatch){ $contents = [regex]::Match($doc,'(?is)(?<=bd: Scheduleb).*?(?=bd: Endb)') New-Item -Path C:tmp1 -Name newtest.txt -ItemType File -Value $contents } Else{ Write-Host "Nothing Found" }

    • It worked if i have only one occurrence but not working in my case because i have multiple occurrence of schedule and end statements. $doc = Get-Content "C:testPS.txt" if(Select-String -InputObject $doc -Pattern "DWSN14624"){ $contents = [regex]::Match($doc,'(?sm)(?=SCHEDULE).*?DWSN14624.*?(?=END).*') New-Item -Path C:tmp1 -Name newtest.txt -ItemType File -Value $contents } Else{ Write-Host "Nothing Found" }

    • Separating the trigger Good Morning from the Start,End markers could lead to false positives in a more complex scenario than originally given. @Saurabh Did I guess right the leadinng numbers colon are not part of the file? You should append a more real life example to your question.
