Today I easily renamed a large number of text files in nested folders with the zsh built-in zmv (man page in zshcontrib). Load it with autoload -U zmv. I ran it with -n to force a dry run until I got the regex right, and the final was: zmv -Q '(**/)(*).txt' '$1$2.md' (zmv -opt searchstring replace string) where -Q renames hidden files also, the parentheses around the search path and filename globs will put those in sub-expression variables, and the variables are then referred to as $1 and $2 in the replace string.
