I\'m trying to replace the word \"owner\" with \"user\" in all file names of my directory (and in all subdirectories).
Ex.
owners_controller => users_
If you don't have rename installed, this should be a reasonable alternative (assuming bash as your shell):
rename
bash
while read entry do mv "${entry}" "${entry/owner/user}" done < <(find . -depth -name '*owner*' -print)
