git log --before =“ 4个月”向我显示3周前已提交的分支。我究竟做错了什么？ [英] git log --before="4 months" show me branches that have commits from 3 weeks ago. what am I doing wrong?

问题描述

所以我有这个代码段，我想用它来筛选出没有特定前缀并且在3个月内没有收到任何提交的分支，以便以后可以将其从我们的遥控器中删除。

so I have this snippet that I want to use to filter out branches that doesn't have a certain prefix and that hasn't received any commits in over 3 months so that I can remove them from our remote later on.

 for k in $(git branch -r | awk -Forigin !'/\/Prefix1\/|\/prefix2\//'); do
  if [ "$(git log -1 --before="3 month" $k)" ]; then
    echo "$(git log -1 --pretty=format:"%ci, %cr, " $k) $k";
  fi;
done

当前的问题是，当我运行此程序时，我看到已收到提交的分支3周前，5个月前，2个月前，1个月前，依此类推，我不知道为什么。

The problem is currently that when I run this I see branches that have received commits 3 weeks ago, 5 months ago, 2 months ago, 1 month ago etc etc and I can't figure out why.

但是，如果我只运行：git log --before = 4 month --pretty = format：％ci，％cr，可以按预期工作。

But if I only run: git log --before="4 month" --pretty=format:"%ci, %cr, " It works as intended.

有人可以给我任何指导吗？

Can anyone give me any guidance?

推荐答案

git日志中的 -1 -1 [过滤器] $ k 将：

The -1 in git log -1 [filters] $k will :

• 展开 git log的历史记录[过滤器] $ k


• 将此历史记录限制为第一行

因此，如果分支的历史记录中有3个月的提交（我想：您的任何分支都有），则 git log -1 --before = 3 month $ k 始终显示1行，这是其历史上第一个提交超过3个月的行。

So if a branch has a 3 month old commit in its history (I would guess : any of your branches does), git log -1 --before="3 month" $k will always show 1 line -- the first commit in its history that is more than 3 month old.

您的前导 [...] 条件将始终为真。

Your leading if [ ... ] condition will always be true.

要解决此问题，您可以限制提交的范围以仅选择每个分支的最前面的提交：

To fix that, you can limit the range of commits to select only the leading commit of each branch :

git log --before="3month" $k^..$k
