Powershell Script that takes username and checks security groups - powershell

Question

I want to create a powershell script that checks a users profile which security groups the user belongs to inside the active directory. Then I want to write it to a file.
I'm having trouble solving this problem.
Example of the expected output.
User1
Security Groups
Domain users
Domain admins...
User2
Security Groups
Domain users
Enterprise admins
New-Item "$home\Desktop\GroupsMembers-list $(get-date -f dd-MM-yyyy).txt"
$users = #("User1", "User2", "User3", "User4")
foreach ($user in $users){
Get-ADPrincipalGroupMembership $user | sort name | select name | Out-File "$home\Desktop\GroupsMembers-list $(get-date -f dd-MM-yyyy).txt"
}

Answer 1

I imagine you could get a bit more creative with it but this could definitely work for you:
$users = #("user1","user2")
foreach ($user in $users){
$groups = Get-ADPrincipalGroupMembership $user | Where-Object {$_.GroupCategory -eq "Security"} | Sort-Object Name | Select-Object -ExpandProperty Name
Add-Content -Path C:\path\to\file.txt -Value #"
$user
Security Groups
----------------------------
"#
foreach ($group in $groups){
Add-Content -Path C:\path\to\file.txt -Value $group
}
}
This is what the output looks like:
user1
Security Groups
----------------------------
Administrators
Domain Admins
user2
Security Groups
----------------------------
Administrators
Domain Admins

Answer 2

I think it will be something like this:
$users = #("User1", "User2", "User3", "User4")
$file= "$home\Desktop\GroupsMembers-list $(get-date -f dd-MM-yyyy).txt"
""| Out-File $file; #Clear content of file
foreach ($user in $users){ ""| Out-File -Append $file; #Add a new line
"$User is in Security groups:"| Out-File -Append $file; # making a Title
"---------------------------------"| Out-File -Append $file; # making a Title
Get-ADPrincipalGroupMembership $user | sort Name | ft -HideTableHeaders Name | Out-File -Append $file #Writing data
}
The txt file will be replaced each time, when running script.
