powershell out-file如何消除每行上的多余空间

Question

I run this command and I get all computer hostnames in the names.txt file. Each hostname in the file is on a separate line, but every hostname is followed with white spaces which cause an issue when I try to read this file. How can I output to this file without getting the white spaces on each line?

Get-ADComputer -Filter * | Select-Object -property name | Sort-Object -Property name | out-file -filepath C:\temp\names.txt  

Answer 1

You have the problem that you don't just have names, you have objects with the property 'name', and you also have the problem that Out-File runs complex objects through some kind of formatting before sending them to the file.

To fix both, expand the name out to just text, and generally use Set-Content instead:

Get-ADComputer -filter * | Select-Object -ExpandProperty Name | Sort-Object | Set-Content C:\temp\names.txt 

or in short form

Get-ADComputer -filter * | Select -Expand Name | Sort | sc C:\temp\names.txt 

or

(Get-ADComputer -filter *).Name | sort | sc C:\temp\names.txt 

Answer 2

Piping it through this should work (before piping to the out-file):

EDIT : Piping through % { $_.name } should convert @{name=VALUE} to VALUE:

 % { $_ -replace ' +$','' } | % { $_.name }

Like this:

Get-ADComputer -Filter * | Select-Object -property name | Sort-Object -Property name | % { $_ -replace ' +$','' } | % { $_.name } | out-file -filepath C:\temp\names.txt

Answer 3

expandproperty should get rid of the @()

Get-ADComputer -Filter * | sort Name | Select -expandproperty Name | %{ $_.TrimEnd(" ") } | out-file -filepath C:\temp\names
