How to automate file copying with renaming in linux?

Question

linux

There is a source of files with a structure like yyyy\mm\Statistics for yyyymmdd.xls
Files in the source are added every working day. It is necessary to copy all xls files containing the words " Statistics for ", but so that the target file does not have it, that is:
Statistics for 20190318.xls -> 20190318.xls
Is it possible to do this with standard tools or maybe there are some third-party utilities suitable for this task?

Answer 1

Here is an example how to copy files from "Statistics for 20190318.xls" format to "20190318.xls"
then tune to your needs, for example, to rename cp, replace it with mv

find -name "*.xls" -exec sh -c 'mv "$1" `echo $1 | grep -o -E "[0-9]+"`.xls' sh {} \;

Answer 2

You can either use standard tools or write a script in any language available in the system.
