linux - Copy or move files to another directory based on partial names in a text file

Question

I want to copy some files from directory A to directory B on basis of partial filenames which are in a text file.

I tried the command below, but it's not working

for fn in $(cat filename.txt); do find . -type -f -name '$fn*' 
    -exec rsync -aR '{}' /tmp/test2 ;

File names are in format abcd-1234-opi.txt, rety-4567-yuui.txt. I have to grep numbers from file names and then copy those files to another folder, I have numbers in a text file.

Can anybody guide me?

If I understand your question correct:

for file in $(<./example); do cp "${file}" /tmp/test2/; done

for file in $(<./example); do find . -type f -name ${file} -exec rsync -aR {} /tmp/test2/ ; ; done
