A (slightly contrived) example: > rsync --e«TAB» Completing file some-file-with-extra-hyphens Completing host a-n-example.local Completing option --cvs-exclude -- auto-ignore files the same way CVS does --delete-excluded -- also delete excluded files on the receiving side --exclude -- exclude files matching pattern --exclude-from -- read exclude patterns from specified file --executability -- preserve executability --ignore-existing -- ignore files that already exist on receiving side --ignore-non-existing --existing -- ignore files that do not exist on receiving side There are various ways to present the completion; I have the simple "keep typing letters" way, but Zsh can also present a table with an entry to highlight.
