Question

Depending on what I am diffing sometimes I want to see several lines (let’s say 10) above and below the +insertions -deletions, sometimes I just want to see a couple of lines surrounding them.

Is there a way to tell git the number of line he should show me?

Answer 1

The option you’re looking for is -U. From the man page:

-U<n>, --unified=<n>

Generate diffs with lines of context instead of the usual three. Implies -p.
