Writing an output on a .txt file on Powershell - powershell

Question

I found a little script to get all the local groups and members and it's working perfectly but I need to write the output on PowerShell.
Trap {"Error: $_"; Break;}
function EnumLocalGroup($LocalGroup) {
$Group = [ADSI]"WinNT://$strComputer/$LocalGroup,group"
"`r`n" + "Group: $LocalGroup"
$Members = #($Group.psbase.Invoke("Members"))
foreach ($Member In $Members) {
$Name = $Member.GetType().InvokeMember("Name", 'GetProperty', $Null, $Member, $Null)
$Name
}
}
$strComputer = gc env:computername
"Computer: $strComputer"
$computer = [adsi]"WinNT://$strComputer"
$objCount = ($computer.PSBase.Children | Measure-Object).Count
$i = 0
foreach ($adsiObj in $computer.PSBase.Children) {
switch -regex ($adsiObj.PSBase.SchemaClassName) {
"group" {
$group = $adsiObj.Name
EnumLocalGroup $group
}
}
$i++
}
I already tried this:
function EnumLocalGroup($LocalGroup) | Out-File -FilePath "E:\PS\Malik\group.txt"
But the code won't start if I do that. I also tried to use this whole Out-File line at the end of the code after the } but doesn't work either and this is the only solution I find on Internet.

If you want to incorporate logging into a function you need to put it into the function body, e.g.
function EnumLocalGroup($LocalGroup) {
....
$foo = 'something'
$foo # output returned by function
$foo | Add-Content 'log.txt' # output to log file
...
}
or
function EnumLocalGroup($LocalGroup) {
...
$foo = 'something'
$foo | Tee-Object 'log.txt' -Append # output goes to log file and StdOut
...
}
Otherwise you have to do the logging when you call the function:
EnumLocalGroup $group | Add-Content 'C:\log.txt'
