我如何绘制一个unix diff命令的结果并排，而不是一个差异？参见下面的例子：
diff /tmp/test1 /tmp/test2 1,4c1,2 < asfdsadf < asdfsad < fsaf < fdsadf --- > asdfsafdsf > saf 6,8d3 < sadf < asdf < sadf 10d4 < fasd 12,13c6,14 < sadfa < fd --- > sadf > sadf > sadf > sadf > sadf > sadf > sadf > sadf > safa
我想有一些像：
diff /tmp/test1 /tmp/test2
1,2
< asfdsadf > asdfsafdsf
< asdfsad > saf
< fsaf
< fdsadf
---
6,14
< sadfa > sadf
< fd > sadf
--- > sadf
> sadf
> sadf
> sadf
> sadf
> sadf
> safa
从man diff，你可以使用-y做并排。
-y,--side-by-side
output in two columns
因此，说：
diff -y /tmp/test1 /tmp/test2
测试
$ cat a $ cat b hello hello my name my name is me is you
让我们来比较它们：
$ diff -y a b hello hello my name my name is me | is you
