The following command lists all files (with lines) that have the mentioned line:
$ grep "\[oow\] running" *.log
However, what I want to know is all the *.log files that do not have that line. Using the
-v option to grep prints innumerous number of other lines. But I only want the file that does not have the mentioned line. How does one normally do this in Unix/Mac (in command line of course)?
