更改 git diff 输出前后的行数

Question

我想增加 git diff 输出更改前后显示的行数。

类似于grep -A3 -B5 ...

Answer 1

根据 git diff --help，git diff 支持与标准 diff 命令相同的参数 w/r/t 上下文：

   -U<n>, --unified=<n>
       Generate diffs with <n> lines of context instead of the usual three. Implies
       -p.

Answer 2

您可以使用 -U 开关来控制 diff 周围上下文的行数：

$ git diff -U5

change no of lines after and before in git diff output
