If you're wondering why your original code didn't work, it's because
the -replace operator uses regular expressions, and "." is a special
character in regular expressions that means "match any character." So, when
you regex-replace "." with the empty string, you're replacing every
character in the string with nothing. You can escape it by using "\."
instead of just ".", but in this case, I'd recommend just using
String.Replace() as suggested by Brandon.
Also as Brandon suggested, a regular expression might serve you better here.
You could try something like this:
gc error_log | foreach {([regex]"(?<app>\w+) exited with error code
(?<error>\d+)\.").Match($_).Groups["error"].Value}
This will give you all the error codes in your file that are in this format.
You could also return a hashtable that includes the name of the app and the
error message -- I only included that to show that you can capture more
information this way than just the error code. Hope this helps.
