How can I batch move a prepended year to the end of a file name?
Untested.
find /path -name '???? - *.txt' -print0 | while read -d ''; do [[ $REPLY =~ (.*)/(....)\ -\ (.*)\.txt$ ]] || continue path=${BASH_REMATCH[1]} year=${BASH_REMATCH[2]} str=${BASH_REMATCH[3]} echo mv "$REPLY" "$path/$str ($year).txt"doneRemove the echo once the generated mv commands look right.
I know you didn't tag it with zsh but you did say shell. Anyway here's how to do it with the zmv function in zsh:
autoload zmv # It's not loaded by defaultzmv -nvw '* - *.*' '$2 ($1).$3'Remove -n when you're happy with the output.
-v makes zmv verbose. -w implicitly makes a group of each wildcard.
