Using the files [1], [2] (around 1.4 MB each) and running the following command:
$ grep -v -f file1 file2 quickly consumes all of my memory (16 GB) and exits with memory exhausted error. I have reports that it behave the same on machine with 180 GB RAM. Well, -F should be used as there are no regexes, but the same worked with grep-2.5.1 and consumed only cca 0.5 GB of RAM. Maybe there is a room for optimization thanks & regards Jaroslav [1] https://jskarvad.fedorapeople.org/grep/file1 [2] https://jskarvad.fedorapeople.org/grep/file2
