A quick, lean standard template for a PowerShell script that includes logging via start-transcript

standard_logging.ps1

## Standard informational header first.
##

## Configuration section next
$maxfoo = 10;
## 

Start-Transcript -Path ".\$(([io.fileinfo]$MyInvocation.MyCommand.Definition).basename.Trim())_exec.log"
###### OR # "$($env:TEMP)\$(([io.fileinfo]$MyInvocation.MyCommand.Definition).basename.Trim())_exec.log"
###### OR # "$($env:LOGS)\$(([io.fileinfo]$MyInvocation.MyCommand.Definition).basename.Trim())_exec.log"


write-output "Ok now do all your stuff. "
write-output "This works well for powershell scheduled tasks, too; no need for redirection operators in the arguments box"


## Then put at the very end of the script:
Stop-Transcript
