如何递归查找目录中最新修改的文​​件? [英] How to recursively find the latest modified file in a directory?

问题描述

似乎 ls 在进行递归调用时没有正确排序文件:

It seems that ls doesn't sort the files correctly when doing a recursive call:

ls -altR . | head -n 3

如何在目录(包括子目录)中找到最近修改的文件?

How can I find the most recently modified file in a directory (including subdirectories)?

推荐答案

find . -type f -printf '%T@ %p
' 
| sort -n | tail -1 | cut -f2- -d" "

对于一棵巨大的树，sort 可能很难将所有内容都保存在内存中.

For a huge tree, it might be hard for sort to keep everything in memory.

%T@ 给你修改时间就像一个unix时间戳，sort -n 数字排序，tail -1 取最后一行(最高时间戳)，cut -f2 -d"" 从输出中去掉第一个字段(时间戳).

%T@ gives you the modification time like a unix timestamp, sort -n sorts numerically, tail -1 takes the last line (highest timestamp), cut -f2 -d" " cuts away the first field (the timestamp) from the output.

正如 -printf 可能是 GNU 唯一的一样，stat -c 的 ajreals 用法也是如此.虽然可以在 BSD 上做同样的事情，但格式化的选项是不同的(-f "%m %N" 看起来是这样)

Just as -printf is probably GNU-only, ajreals usage of stat -c is too. Although it is possible to do the same on BSD, the options for formatting is different (-f "%m %N" it would seem)

我错过了复数部分；如果您想要更多 最新文件，只需增加 tail 参数即可.

And I missed the part of plural; if you want more then the latest file, just bump up the tail argument.
