给定一个 git repo,我需要生成每个版本控制文件的最后修改日期的字典,作为映射到其文件路径的 unix 时间戳。就 git 而言,我需要最后修改日期 - 而不是文件系统。

为了做到这一点,我想让 git 输出受版本控制的所有文件的列表以及每个文件的作者日期。如果他们的输出在每一行都包含时间戳,那么来自git ls-filesor的输出将会是完美的。git ls-tree -r master

有没有办法从 git 获取这个输出?

更新更多上下文:我有一个当前实现,它由一个 python 脚本组成,它遍历源代码控制下的每个文件并对每个文件执行git log一个,但我发现它不能很好地扩展。存储库中的文件越多,git log我必须拨打的电话就越多。所以这导致我寻找一种方法来从 git 收集这些信息,调用次数更少(理想情况下只有 1 个)。

缩放不是这个问题:

#!/bin/sh
temp="${TMPDIR:-/tmp}/@@@commit-at@@@$$"
trap "rm '$temp'" 0 1 2 3 15
git log --pretty=format:"%H%x09%at" --topo-order --reverse "$@" >"$temp"
cut -f1 "$temp" \
| git diff-tree -r --root --name-status --stdin \
| awk '
        BEGIN {FS="\t"; OFS="\t"}
        FNR==1{++f}
        f==1  {at[$1]=$2; next}
        NF==1 {commit=$1; next}
        $1=="D"{$1=""; delete last[$0]; next} # comment to also show deleted files
              {did=$1;$1=""; last[$0]=at[commit]"\t"did}
        END   {for (f in last) print last[f]f}
 ' "$temp" - \
| sort -t"`printf '\t'`" -k3

我编写了以下脚本来为每个文件输出路径、短标签和日期。

我要做的是运行git ls-files并将它们全部添加到一个数组中,然后运行git log $date_args --name-only,然后解析该输出并从数组中删除这些文件,同时将日期信息添加到字典中,并在数组为空时停止处理。

干得好:

git ls-files -z | xargs -0 -n1 -I{} -- git log -1 --format='%at {}' {}

这适用于bash并且可能sh
