Recursively list only files; grep them with g to get full path, filename, and line number; protect against John's semicolon trick by quoting each file.
walk -f | sed 's,^,g '^$1^' '',;s,$,'',' | rc walk apparently completely omits from its output files with a single-quote in their names, and does not quote files with embedded semicolons. ls lists them both quoted, with the embedded single-quote doubled. All this tested in p9p.
