给定一个 git 存储库,我需要生成每个版本控制文件的上次修改日期的字典,作为映射到其文件路径的 unix 时间戳。就 git 而言,我需要上次修改日期 - 而不是文件系统。
为了做到这一点,我想让 git 输出版本控制下所有文件的列表以及每个文件的创作日期。如果git ls-files
或git ls-tree -r master
的输出在每行都包含时间戳,则它们的输出将是完美的。
有没有办法从 git 获取此输出?
更新以获取更多上下文:我有一个当前的实现,该实现由一个 python 脚本组成,该脚本循环访问源代码管理下的每个文件并对每个文件执行git log
,但我发现它不能很好地扩展。存储库中的文件越多,我必须进行的git log
调用就越多。因此,这促使我寻找一种方法来从 git 收集此信息,调用更少(理想情况下只有 1 次)。
受版本控制的所有文件的列表以及每个文件的创作日期
扩展不是这个问题:
#!/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输出每个文件的路径、短主题标签和日期。

做的是运行git ls-files
将它们全部添加到数组中,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,并在数组为空后停止处理。
你去吧:
git ls-files -z | xargs -0 -n1 -I{} -- git log -1 --format='%at {}' {}
这适用于bash
,可能sh
.
