Most errors which occur in your working scripts are likely to be “non-terminating”.  This means that Monad just reports the error and the command keeps running.  (“Terminating” errors such as syntax errors will halt the command and, in some cases, the entire script; see http:\/\/blogs.msdn.com\/monad\/archive\/2005\/11\/15\/493102.aspx<\/a> for more details.). <\/p>\n

This Blog describes how to handle non-terminating errors.  You may choose to modify the action that occurs when a non-terminating error occurs or you may choose to collect non-terminating errors in a variable.  If you collect non-terminating errors in a variable, your script can check to see if any the prior command emitted any non-terminating errors.<\/p>\n

Consider:<\/p>\n

MSH C:\\temp\\monad> remove-item nosuchfile.txt;write-host “done”
remove-item : Cannot find path ‘C:\\temp\\monad\\nosuchfile.txt’ because it does not exist.
At line:1 char:12
+ remove-item  <<<< nosuchfile.txt;write-host “done”
done
MSH C:\\temp\\monad><\/font> <\/p>\n

Even though the file was not found, the script just kept on running.  This is often the case with scripts which are syntactically correct but encounter operational errors.  So, what can you do to cause a script to react to problems it might encounter?<\/p>\n

(1) -ErrorAction <\/p>\n

You can change how Monad reacts to non-terminating errors with the “-ErrorAction” ubiquitous parameter (“-ea” is the alias).  Your options are SilentlyContinue, Continue, Stop, and Inquire (also see http:\/\/blogs.msdn.com\/monad\/archive\/2005\/11\/11\/491967.aspx<\/a>):<\/p>\n
