git - 揪出来改你代码的人

先查找某个文件的历史修改记录,然后根据关键信息匹配对应的更改,根据具体情况显示更改的前N行,就能查到commit信息了!

比如我要查看是谁删掉了我requirements.txt文件的这行代码openpyxl==3.1.2

执行下面的命令就查到commit信息了

 ➜  e100_v2 git:(3.3/dev) git log -p -- requirements.txt | grep -B 15 '\-.*openpyxl==3.1.2'

解释一下:

git log -- <filepath> 可以查看某个文件的修改记录 -p 参数会显示每次提交的内容

利用grep进行关键字搜索, -B <n> 参数显示结果行+结果行前n行的内容.

上面的命令结合grep做的操作. 那么git本身能不能对修改内容进行模糊匹配?

查了下有的, git log -G 可以做正则匹配

➜  e100_v2 git:(3.3/dev) git log -G'openpyxl==3.1.2' -p

这个查出了添加和删除时的两个commit, 有没有办法只显示添加的或者删除的?
