Scan line and extract specific info

PowerShell Help
1

Hello Everyone,

I need to create a script which can scan through a config file, then extract some specific info and write them into new files.
I am still a beginner, so it may appear to be an easy thing to most. I appreciate any kind of help you can offer on this.

Below are few lines from the input file:

BEGIN INITIALIZATION REGION=HALOC010
START REGION=HALOC010
BEGIN EXECUTE LCAQPRO1
BEGIN EXECUTE LCAQPRO2 GROUP=OACI410G
BEGIN EXECUTE PROGRAM=ICP9120 GROUP=KEE202
BEGIN EXECUTE PROGRAM=ICP9121 GROUP=KEE202

I need to list out the programs and scripts from the config file and create two new files. (Scripts are followed by the word 'EXECUTE ’ and programs are the ones followed by ‘PROGRAM=’)

File#1 should look like
LCAQPRO1
LCAQPRO2

File#2 should look like
ICP9120

Here is how I am trying to do, but it’s definitely not the right way. And the config file can have any number spaces between each word.

cat conf.file | where { $_ -match "EXECUTE"} > temp1.file
cat temp1.file | where { $_ -match "PROGRAM"} > temp2.file
type temp1.file | findstr /V /C:"PROGRAM" > temp3.file
Get-Content temp3.file | ForEach-Object { 
    $_.Split("EXECUTE", [System.StringSplitOptions]::RemoveEmptyEntries) 
} | Set-Content temp4.file

Thanks.

The code below is a little clunky but should work for you, barring any other format anomalies in your conf file. If you use -split in front of the string it uses the default of any white space so the number of spaces and/or tabs shouldn’t affect it.

$conffile = "config.file" #use full or relative paths if not in working dir
$temp1 = "temp1.file"
$temp2 = "temp2.file"

$conf = Get-Content -Path $conffile 
$conf | % {
    if($_.Contains("EXECUTE PROGRAM=")) {
        (-split ($_ -Split("=")))[3] | Out-File -FilePath $temp2 -Append
    }
    elseif($_.contains("EXECUTE")) {
        (-split $_)[2] | Out-File -FilePath $temp1 -Append
    }
}

Thanks for your reply. It does work, however the data in the cofig file is not very well formatted. There are multiple spaces, comma and semicolon at random places. I am trying to get rid of them first, and then will use the code you shared.
