However, this time I want to do it with Eshell. My own attempt, works, but I think there should be an easier way: $ listify *.jpg $ setq my-files $$ $ setq my-numbers $(number-sequence 1 (length my-files)) $ setq my-pairs $(mapcar* 'cons my-files my-numbers) $ for pair in $my-pairs { setq a (car pair); setq b (cdr pair); mv $a "$b".jpg } PS: I already posted this on Emacs Stack Exchange .
