Regex For Log Parsing -


i trying find of exceptions in log not of type invalidargumentexception. our log writes out lines following:

class:       invalidargumentexception

the regex trying use is:

/class:.*(!invalidargument)exception/

essentially, start word class:, allow characters after class not equal invalidargument, , include word exception

thank help.

one possibility negative behind:

/^class:.*?(?<!invalidargument)exception/

test grep -p:

kent$  echo "class:   foo    invalidargumentexception class: bar nullpointerexception"|grep -p '^class:.*?(?<!invalidargument)exception' class: bar nullpointerexception
