Ignore hosts file in ZSH ssh/scp tab-complete

hostszsh

I use a hosts file to block ads/malware domains. When I use ssh or scp in zsh and try to tab-complete, it takes a good 5-10 seconds before anything appears and what does appear is usually a list of 20+ domains I have blocked, and buried in there is the file I need.

I've search online quite a bit, and found helpful hints of how to add this sort of auto-completion, but I can't figure out how to remove it. I basically never want the tab-complete to search my hosts file (I use known-hosts for the servers I actually do want to tab-complete to).

This is on OS X.

Try adding the following to your zshrc

zstyle ':completion:*' hosts off

Shell – What’s the magic that allows me to tab-complete remote files as I type an scp command

Oooh, I found an explanation.

To quote the relevant part:

The zsh shell comes with (more than one) great feature(s), such as remote tabcompletion. If you for example want to copy a file over scp, simply hit tab at any part of the filename on the remote host. zsh is able to establish an ssh session on the background, and fetch the related information for you, so you can tabcomplete trough the remote files.

The post goes on to show some zstyle declarations that achieve the completion, but I would strongly suggest using a zsh package such as the aforementioned oh-my-zsh to get this stuff maintained by the OSS community for you.

Something seemingly relevant, as seen on my system in my .oh-my-zsh dir:

$ ack scp 
plugins/common-aliases/common-aliases.plugin.zsh
85:zstyle -e ':completion:*:(ssh|scp|sftp|rsh|rsync):hosts' hosts 'reply=(${=${${(f)"$(cat {/etc/ssh_,~/.ssh/known_}hosts(|2)(N) /dev/null)"}%%
[# ]*}//,/ })'
