Even if it is an old question:

Saving TinyMCE Base64 images with dragonfly
I usually use rs+[tab] to get rsync but it's showing three options (on a new system):

➜  $ rs
     rsh       rsync     rsyslogd


I seldom use rsh or rsyslogd - how can I prevent these from appearing as matches in the autocompletion list in zsh?
