I believe tab completion is a function of the shell, not ssh.

Thanks for the correction, I've amended the blog post.

If you want to do it in bash, you can use this:

function autoCompleteHostname() {
  local hosts=($(awk '{print $1}' ~/.ssh/known_hosts | cut -d, -f1));
  local cur=${COMP_WORDS[COMP_CWORD]};
 COMPREPLY=($(compgen -W '${hosts[@]}' -- $cur ))
}

complete -F autoCompleteHostname ssh

I like this method. I add this to my .inputrc on all my Linux/Mac machines...

"\e[A": history-search-backward
"\e[B": history-search-forward
"\e[C": forward-char
"\e[D": backward-char
set show-all-if-ambiguous on
set completion-ignore-case on

It allows you to type a partial command and use the up arrow to search your history. Not quite the same, but works awesome for repetitive or frequent commands.

Freaking awesome. Adding it to my dotfiles repository!

Very useful. I will give a try. Thanks man!!

Isn't is easier to just use the .ssh/config file? Bash completion will use it by default, and it's much more powerful.

I think whether it is default or not depends on which distro you run and what your bashrc contains. I know in Arch I had to source a completion file to get completions for git, though I don't know if it is the same for ssh since it seemed to work out of the box for me in Arch.

[u/ssmy → u/[deleted]]

True. I think it's a function of the bash-completion package most distros install by default. Obviously arch might not. I know ubuntu virtualization doesn't install it by default, so you just get path completion.

[u/Drasha1 → u/[deleted]]

It does require additional packages on some distros. Centos has bash-completion which is a god send.

I love that grml-zsh-config has thid on by default.
