diff 命令标签格式

Question

是否可以使用 diff 或 sdiff 命令或任何其他工具在两个 diff 文件上获取 header 或 label。下面是一个例子，我们有一个比较 100 多个文件的脚本，所以很高兴知道我们正在比较的是哪个文件..

目前：

# diff -y --suppress-common-lines /tmp/file1 /tmp/file2
    how are you                                                   | How are you sir
    xxxxxxx

我想要 header 或标记类似下面的东西，这样它在报告中看起来不错，否则我必须做 echo 等..让它工作

# diff -y --suppress-common-lines /tmp/file1 /tmp/file2
    [file1]                                                            [file2]
  how are you                                                   | How are you sir
  xxxxxxx
                                                   <

Answer 1

试试这个或者把它添加到你的 ~/.bashrc:

function mydiff() { echo -e " [${1##*/}]\t\t\t\t\t\t\t[${2##*/}]"; diff -y --suppress-common-lines  ; }

并使用这个：

mydiff /tmp/file1 /tmp/file2

Answer 2

您可以使用 vimdiff 或 vim -d 检查文件差异。

vimdiff /tmp/file1 /tmp/file2
