Converting webpages from UTF-8 to ISO-8859-1 in linux

Question

Anyone have a neat trick on how to convert a number of php and html files from UTF-8 to ISO-8859-1 in linux (Ubuntu)?

Answer 1

Ubuntu has recode

$ sudo apt-get install recode
$ recode UTF-8..latin1 *.php

Recursively, thanks to Ted Dziuba:

$ find . -name "*.php" -exec recode UTF-8..latin1 {} \;
