Greetings,
I have found what looks like a bug in grep. I have not been able to test it on
other systems, but for the record, I am using SuSE's Novell Linux. I haven't
noticed this bug before, but then again, I hadn't tried to grep through a 40
Gigabyte file before.
Steps to see the bug:
grep -i someword some40Gigabitefile.txt > results.txt
looking at results, we could for example see:
40047878321- someword
Now do this:
xxd -s 40047878321 | less
This /should/ take us right to the offset where the word appears. For the most
part it does. But once the word is found really deep into the file - ie: the
byte offset gets huge - those offsets have nothing to do with reality.
Let me know if you have already discovered this, if it is fixed, or what I'm
doing wrong to make this happen.
Thanks,
Karsten Johansson
