Zsh does not supply a completion function for tail. Thus, it should fall back to file-completion for programs it doesn't know for any better. You can try this: % zsh -f % autoload -Uz compinit; compinit % tail -F <tab> and try to reproduce the issue with a clean zsh instance with just the completion system loaded. You'll see that you can't; because I can't. My guess is, that you've got a completion handler configured for tail. Like ‘_gnu_generic’. Try this (from a failing shell of yours): % print ${_comps[tail]} and that will most likely print ‘_gnu_generic’. Long story short: This is not a bug in Debian's zsh package. But rather in your configuration, since it assumes _gnu_generic can handle the --help output of current GNU tail versions. Which it apparently can't. You could argue, that this might be considered a bug in zsh's _gnu_generic function; but really, that's a hack to try and parse completion information from --help of any given command you assign to it. If that output changes in an incompatible way, the function is screwed. It's a best-guess solution rather than something sustainable. I would suggest dropping the completion function assignment from your configuration.
