How to multiple rename with bash
Sorry the wiseman, I can't remember that guy who post this knowledge. ( he 's alway great ). In your command line ( bash ) do $ for file_name in *. ; do mv $file_name ${file_name/ / }; done; for example $ for f in *.sql; do mv $f ${f/.sql/.dump}; done; Then every sql files in your current folder will be .dump files hahaha :)
