Ah ha, then checkmate, $ recode -l|grep -i base64 /Base64 64 b64 I.e., you must either 1. Make a separate quoted-printable(1) command too, just to be fair. 2. Leave a note on the base64(1) man page saying that if one is looking for quoted-printable(1) try recode instead... however this isn't a good place to leave such a note... hmmm OK, whatever. I'll try to remember recode.
