and i want to use powershell to capture the group information and so that i can get the groupname and run another command to loop through the group name. example output is as per below.
GRP001Temp
GRP002-PHY01
GRP003-PHY02
GRP001-PRD-ORA
GRP001-PRD-SAP
GRP002-PRD-SAP
Hope you can help me with my problem. Thank You in advance.

Answer 1

if every group is in the Role "Primary" one easy way might be the following statement:
get-content Demo.txt | where { $_ -match "Primary" } | % { $_.Split(" ")[0] }
It gets the lines which contain the word "Primary" and takes the first word (in your case the group name)

Answer 2

You can split the output by the linebreak and loop over the result.
If a line starts with Name, split the next line by a space and write the first element to the output.
Something like:
param($output)
$lines = $output -split [Environment]::NewLine
$name = $false
foreach($line in $lines) {
if($name) {
($line -split ' ')[0] | Write-Output
$name = $false
}
if($line.Startswith('Name')) {
$name = $true
}
}

Answer 3

Obviously you are after the first word following the Header
Name Target Status Role Mode Options
Not including the false header
Name ID Type Status Options Policy
the other answers aren't excluding.
So I'd split the file content with a RegEx by this Header into sections and skip the first one.
Then split each section into words separated with white space \s and get the first [0]
(Get-Content .\SO_53154266.txt -raw) -split "(?sm)^Name\s+Target.*?`r?`n" |
Select-Object -skip 1|
ForEach-Object { ($_ -split '\s')[0] }
Sample output:
GRP001Temp
GRP002-PHY01
GRP003-PHY02
GRP001-PRD-ORA
GRP001-PRD-SAP
GRP002-PRD-SAP
