在与某些文件大小匹配的目录中查找最新文件

Question

I need to find the most recently modified file in a directory that matches 3.0 MB.

First Attempt

ls -t /home/weather/some.cool*.file | head -n +1 | grep "3.0M"

Second Attempt

find /home/weather/ -maxdepth 1 -type f -name "some.cool*.file" -size 3M -exec ls -t "{}" +; | head -n +1

Am I close?

Answer 1

I hope this is of some use -

ls -ltr --block-size=MB | grep 3MB

The latest modified files will be displayed at the bottom of the output.

The -r flag shows the output in reverse order and the --block-size=MB will show the size of files in MB.

Answer 2

这应该工作：

ls -lh --sort=time /path/to/directory/*.file | grep "3.0M" | head -n =1
