I think the thing here is that he doesn't need to know the position,
just that the pattern exists, and the context in which it exists.
I use grep like this all the time, although admittedly I'm using it
on the output of strings. You can't really search the output of
something such as, say, 'hexdump -c', because of its formatting.
grep is about the only useful tool for looking for patterns on streaming
output. sed is far too unwieldy for such a task.
I must admit I don't quite grok for what he's searching, but I do think
that there's something to being able to grep through files, i.e.
grep foo *.o | grep -v bar
main.o: ~r}iv0LMfoo@$#039c @(#) bar.c
main.o: _h)@#$foo: cannot open bar file %s
This would not work on output such as:
main.o: "foo" found.
Is this any clearer?
