• Continue: Display an error and keep doing.

• SilentlyContinue: Don't display an error and keep going. (This is the setting I wish many small children possessed – "Be quiet, keep going.")

• Stop: Produce a terminating error and quit.

So the basic idea is that whenever you anticipate an error, you set the error action to "Stop". That way, any non-terminating errors become trappable exceptions.

Setting the Error Action

Unfortunately, dig up some scripts on the Internet (perhaps at http://poshcode.org, a popular community script repository) and you'll too often see this right at the top of the script:

Never Do This

• $ErrorActionPreference = 'SilentlyContinue'
