How to use PowerShell to remove extra spaces at the end of a line in a text file?

Answer 1

There are several approaches, but it is quite simple:

$content = Get-Content file.txt
$content | Foreach {$_.TrimEnd()} | Set-Content file.txt

You may need to configure the parameter Encodingin the Set-Content cmdlet to get the file in the desired encoding (Unicode, ASCII, UTF8, etc.).

Answer 2

For small files (less than 250 MB) you can use:

$file = "Log20130820"

Get-Content $file  | Foreach {$_.TrimEnd()}  | Set-Content "$file.txt"

For files that are too large, the script will exit with an OutOfMemoryException.
