Export powershell file to text file

I have a foreach loop inside my powershell script with prints $ outputs on the shell during each iteration. There are many many outputs, and the number of entries displayed by the shell is limited. I want to export the output to a text file. I know how to do this on the command line. How is this possible in powershell?

FYI, I use a batch command script from the command line to run a powershell script as

powershell c:\test.ps1 c:\log.log

You can always redirect exe output to such a file (even from cmd.exe):

powershell c:\test.ps1 > c:\test.log

$logFile = 'c:\temp\test.log'
"Executing script $($MyInvocation.MyCommand.Path)" > $logFile
foreach ($proc in Get-Process) {
    $proc.Name >> $logFile
}
"Another log message here" >> $logFile
