Linux - 有没有办法获取目录的文件大小，但只包括最后修改/创建日期为 x 的文件？

Question

as per title I am trying to find a way to get the file size of a directory (using du) but only counting the files in the directory that have been created (or modified) after a specific date.

Is it something that can be done using the command line?

Thanks:)

From @Bodo's comment. Using GNU find:

find directory/ -type f -newermt 2021-11-25 -printf "%s\t %f\n" | \
awk '{s += $1 } END { print s }' | \
numfmt --to=iec-i

1. find looks in in directory/ ( change this )
2. Looks for files ( -type f )
3. that have a newer modified time than 2021-11-25 ( -newermt ) ( change this )
4. and outputs the files's size ( %s ) on each line
5. adds up all the sizes from the lines with awk {s += $1 }
6. Prints the results END { print s }
7. Formats the byte value to human readable with numfmt 's --to=iec-i
