Powershell Regular Expression script question

I am trying to write a script to read in a test file, search for just the user and return that.

SOMEDOMAIN\SomeUser             Full Control[aasdfa]
SOMEDOMAIN\SomeUser             Partial Control[aasdfa]
SOMEDOMAIN\SomeUser             Full Control[aasdfa]

I have some of the code needed and I also have the a regex statement that works.    I am getting caught on the output of $Matches
When I run the code and check $matches is only contains the last item found/returned.

I know I am missing something simple, any insight would be appreciated :)



Get-Content file.txt |where-object{$_ -match '\S*\s'}

This executes with an implicit loop:
Get-Content file.txt |where-object{$_ -match '\S*\s'}

Open in new window

Since Get-Content returns an array, all you'll have in $Matches is the last value. If you need to parse Matches it would be wies to execute this as an explicit ForEach-Object loop:
Get-Content file.txt | ForEach-Object {
  If ($_ -match '\S*\s') {
    # Do things with $Matches
  }
}

ok.   I am sure I am missing something simple, but what if I just want to write this to the host  ie   write-host $matches.value.


When I do this I get nothing back.   Thoughts?

$Matches is a HashTable, it doesn't have a property explicitly called "Value".

I think you want:

$Matches[0]

Which returns the first match, at Key 0.
