Linux find 命令，无论时间跨度，递归查找 10 个最新文件

Linux find command, find 10 latest files recursively regardless of time span

提问by Dejan Marjanovic

What have I tried so far...

到目前为止我尝试了什么...

Command:

命令：

find . -type f -ctime -3 | tail -n 5

Result:

结果：

./Mobilni Telefoni/01. Box Update/05. DC Unlocker Client/dc-unlocker_client-1.00.0857.exe
./Mobilni Telefoni/01. Box Update/39. Z3X Box/01. Update/01. Samsung Box/SamsungTool_12.4.exe
./Mobilni Telefoni/10. Nokia/1. SRPSKI  HRVATSKI  JEZICI/BB5/3xx_Series/Asha 300/06.97/rm781_06.97_ppm_d.rar
./GPS Navigacije/01. Garmin/03. Garmin Other/garmin_kgen_15.exe
./GPS Navigacije/01. Garmin/03. Garmin Other/test.txt

This output is OK, doesn't work good if I put wider time span. (notice I use -ctime and not -mtime because some uploaded files are modified few years ago)

这个输出没问题，如果我把时间跨度更宽，效果会不好。（注意我使用 -ctime 而不是 -mtime 因为几年前修改了一些上传的文件）

Problem is that files can be uploaded once a month, or once in a year, and I still need to get 10 latest files, regardless of time span.

问题是文件可以一个月上传一次，也可以一年上传一次，我仍然需要获取 10 个最新的文件，无论时间跨度如何。

If it can't be done, does tailonly limit output, or somehow just fetches number specified without huge performance impact on large number of files.

如果无法完成，则tail只会限制输出，或者以某种方式仅获取指定的数字，而不会对大量文件产生巨大的性能影响。

By using command from one answer on SO, I was able to get the files but some files were missing...

通过使用 SO 上的一个答案中的命令，我能够获取文件，但某些文件丢失了...

find . -type f -printf '%T@ %p\n' | sort -n | tail -10 | cut -f2- -d" "

File garmin_kgen_15.exeis missing because it was created in 2008, but it was uploaded in last 24 hours.

文件garmin_kgen_15.exe丢失，因为它是在 2008 年创建的，但它是在过去 24 小时内上传的。

I was told that this is the solution:

有人告诉我这是解决方案：

find . -type f -printf "%C@ %p\n" | sort -rn | head -n 10

The key point is the printf %C@placeholder, which is the -ctimeone. I found it by reading man find.

关键点是 printf%C@占位符，它是-ctime一个。我是通过阅读找到的man find。
