获取受git monorepo最近提交影响的所有第一级目录的列表

问题描述

限时删除！！

我目前正在使用monorepos，并且尝试检索列表中自给定提交以来受影响的所有1级子文件夹.

I am currently playing with monorepos and I am trying to retrieve a list all 1 level subfolders in the repo which are impacted since a given commit.

到目前为止，我可以检索受git diff --name-only $COMMIT_ID..head

So far I can retrieve all the files impacted using git diff --name-only $COMMIT_ID..head

使用git diff --name-only $COMMIT_ID..head | xargs -L1 dirname我设法只获取文件夹名称.

Using git diff --name-only $COMMIT_ID..head | xargs -L1 dirname I manage to get only the folder names.

要删除所有重复的内容，我将sort | uniq添加到了组合中:git diff --name-only $COMMIT_ID..head | xargs -L1 dirname | sort | uniq

To remove all the duplicates I added sort | uniq to the mix: git diff --name-only $COMMIT_ID..head | xargs -L1 dirname | sort | uniq

我现在所要做的就是确保仅检索第一级文件夹，即project1而不是project1/src和project1/lib

All I need now is to ensure I only retrieve the first level folders i.e. project1 not project1/src and project1/lib

我尝试了几种选择，但到目前为止，我还没有设法将其保持为一体.

I have tried a few options but I have not managed to keep it as a one liner so far.

推荐答案

以下是awk

git diff --name-only $COMMIT_ID | awk -F'/' 'NF!=1{print $1}' | sort -u

• -F'/'将定界符字段设置为斜杠/

• NF!=1{print $1}如果行中包含斜线/，则会打印出第一级，即第一级目录名称，这会滤除第一级中存在的文件

  • -F'/' sets the delimiter field to slash /

  • NF!=1{print $1} prints out the first field which is the first level directory name if the line contain slashes /, this filters out files that exists in the first level

    readme.md          NF==1
    project1/file      NF==2
    project2/src/file  NF==3
    

  • sort -u结合了排序和唯一性

  • sort -u combined sort and unique
