from `man grep`:
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching lines. Places a
line containing a group separator (--) between contiguous groups of
matches. With the -o or --only-matching option, this has no effect and
a warning is given.
-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines. Places a
line containing a group separator (--) between contiguous groups of
matches. With the -o or --only-matching option, this has no effect and
a warning is given.
-C NUM, -NUM, --context=NUM
Print NUM lines of output context. Places a line containing a group
separator (--) between contiguous groups of matches. With the -o or
--only-matching option, this has no effect and a warning is given.
