I have found an corner case issue while executing the shell command for getting
the new exceptions in the logs. The problem could see whenever the log files
are empty and trying to get the new exceptions count, it returns the output is
0 ,however it returns the exitcode is 1 instead of 0. grep -vc in the command
is not giving the expected exitcode because its not handling the multiple in
options.
