grep -C1 pattern
prints
file-lalala
file:anywhere in line there is pattern
file-lalalalala
--
file-lalalalala
...
with sed it will be:
file:lalala
file:anythere in line there is pattern
file:lalalalala
file:--
file:...

You should answer them -- use find. grep with option -r cannot do a lot
of things, that find + grep can, for instance, I often do something
like:
find . -name '*.h' | xargs grep -w uint32_t
find intended for finding files, grep -- for grepping them :-)
