powershell-3.0

问题 I would like to be able to find all blanks from a CSV file and if a blank character is found on a line then should appear on the screen and I should be asked if I want to keep the entire line which contains that white space or remove it. Let's say the directory is C:\Cr\Powershell\test . In there there is one CSV file abc.csv .

问题 I'm new to Power Shell and I'm testing some commands and ideas. I'm stuck on what I feel should be pretty simple. I want to pull the names of computer objects in AD in to a file. The method I'm trying so far is this $computers = Get-ADComputer -Filter * | Format-List name write($computers) | Out-File -FilePath .\computers.txt the issue I have with this though is that the file that is output looks like this name : SERVER1 name : SERVER2 name : WORKSTATION1 name : WORKSTATION2 And I'm looking
