Bash: recursively copy and rename files

Question

I have many files whose names end in "_100.jpg". They are distributed in subfolders / subfolders. Now I want the trick to recursively copy and rename all of them in order to have the suffix "_crop.jpg". Unfortunately, I am not familiar with bash scripts, so I don’t know how to do this. I googled and tried the find command with the -exec option, but no luck.

Help me. Thank.

Answer 1

  find bar -iname "*_100.jpg" -printf 'mv %p %p\n' \
    | sed 's/_100\.jpg$/_crop\.jpg/' \
    | while read l; do eval $l; done
