Git：如何列出版本控制下的所有文件及其作者日期？ [英] Git: how to list all files under version control along with their author date?

问题描述

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。对于git而言，我需要最后的修改日期 - 而不是文件系统。

为了做到这一点，我想让git输出一个列表版本控制下的所有文件以及每个文件的作者日期。从 git ls-files 或 git ls-tree -r master 的输出将是完美的，前提是它们的输出包含时间戳

有没有办法从git获得这个输出？

Update for更多的上下文：我有一个当前的实现，它包含一个python脚本，它遍历源代码管理下的每个文件并在每个文件上执行 git log ，但是我发现这并不好。回购中的文件越多，我必须进行的 git log 调用越多。因此，这导致我寻找一种方法来从git收集这些信息的次数更少（理想情况下只有1次）。 解决方案

版本控制下的所有文件以及每个文件的作者日期列表

缩放并不是问题用这个：

 ＃！/ bin / sh 
 temp =$ {TMPDIR： -  / tmp} / @@@ commit-at @@@ $$
 traprm'$ 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;下一个} 
 NF == 1 {commit = $ 1;下一个} 
 $ 1 ==D{$ 1 =;删除最后[$ 0];下一步}＃注释也显示已删除的文件
 {did = $ 1; $ 1 =; last [$ 0] = at [commit]\ tdid} 
 END {for（f in last）print last [f] f} 
'$ temp -  \ 
 | sort -t`printf'\t'`-k3 
  

Given a git repo, I need to generate a dictionary of each version controlled file's last modified date as a unix timestamp mapped to its file path. I need the last modified date as far as git is concerned - not the file system.

In order to do this, I'd like to get git to output a list of all files under version control along with each file's author date. The output from git ls-files or git ls-tree -r master would be perfect if their output had timestamps included on each line.

Is there a way to get this output from git?

Update for more context: I have a current implementation that consists of a python script that iterates through every file under source control and does a git log on each one, but I'm finding that that doesn't scale well. The more files in the repo, the more git log calls I have to make. So that has led me to look for a way to gather this info from git with fewer calls (ideally just 1).

解决方案

a list of all files under version control along with each file's author date

Scaling isn't a problem with this one:

#!/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
