Easy REGEXP question #2

I am applying this regexp pattern
File Not Found|LRM\-|Error|Ora\-|SP2\-|FAIL|RC\s*=\s*-?[123456789]+

to look for errors in a log using this function...

Send_Mail_OnError()
{
  #For each line in regex_patterns.txt file,
  #the regular expression-like will fire on the file $error_log
  #if any line returns true, then we will step into the if...
  #Be advised!! Passing a null value in $error_log causes an indefinite hang.
  if egrep -i -s -f $root_dir/regex_patterns.txt $error_log; then
    #For each email address in $emaillist, send and email...
    Send_Mail
  fi
}

This works well for all cases except a single job which sometimes returns the following two lines within the file...

0 Rows not loaded due to data errors.
0 Rows not loaded because all WHEN clauses were failed.

So I think I want to use the results from an exclusionary egrep call first... maybe something like this...


Send_Mail_OnError()
{
  #For each line in regex_patterns.txt file,
  #the regular expression-like will fire on the file $error_log
  #if any line returns true, then we will step into the if...
  #Be advised!! Passing a null value in $error_log causes an indefinite hang.
  if egrep -i -s -f $root_dir/regex_patterns.txt [egrep -v '0 Rows not loaded due to data errors\.|0 Rows not loaded because all WHEN clauses were failed\.' $error_log]; then
    #For each email address in $emaillist, send and email...
    Send_Mail
  fi
}

Could someone help me with this syntax? Am I on the right track?

Thanks!!
