如何将匹配模式的文件复制到名称中有模式的子目录

Question

I have following directory structure:

folder-1.2.3/subA/subB/file.txt
folder-1.2.3/subA/subB/other_sub/file2.txt
folder-1.2.4/subA/subB/file.txt
folder-1.2.4/subA/subB/other_sub/file2.txt

I want to match all paths starting with folder-*/subA/subB and copy its content to /new_dst/prefix-* where * is matched string (1.2.3 or 1.2.4 in my case). The outcome would be:

new_dst/prefix-1.2.3/file.txt
new_dst/prefix-1.2.3/other_sub/file2.txt
new_dst/prefix-1.2.4/file.txt
new_dst/prefix-1.2.4/other_sub/file2.txt

I can use any standard linux command (cp, find, grep, aws, sed..). My initial idea was to use find ( find. -path "folder-*/subA/subB" ) but I don't have direct access what pattern was matched only the whole path. That's why I tried to parse it through sed (for example .. -exec sed -i "s/folder-//g" ) but it's starting to look more complicated than it should be.

Suggesting first to locate the desired files using find command and -path option.

 find root-folder -path "*/subA/subB/*" -name "*.txt"

Once your files are located. Feed the found files into cp command.

 cp $(find root-folder -path "*/subA/subB/*" -name "*.txt") target-folder
