It's been in doc/EXAMPLES for years:

If you've got a lot of spare disk space to trade for performance and the
hash type of your password files is relatively slow, you may use John's
"unique" utility to eliminate any duplicate candidate passwords:

	john --wordlist=all.lst --rules --stdout | unique mangled.lst
	john --wordlist=mangled.lst mypasswd

If you know that your target hash type truncates passwords at a given
length, you may optimize this even further:

	john --wordlist=all.lst --rules --stdout=8 | unique mangled8.lst
	john --wordlist=mangled8.lst mypasswd
