Errors and Logging

Stop soft failures from lying to you.

If it ran unattended, the log is the truth.

Soft errors hide damage. Set $ErrorActionPreference = 'Stop' in scripts you care about so failures become visible. Log timestamps so last Tuesday’s run is still readable.

try {
  Copy-Item .\a.txt .\backup\a.txt -ErrorAction Stop
  Write-Log "copied a.txt"
} catch {
  Write-Log "FAILED: $($_.Exception.Message)"
  throw
}
