Hostname tab-completion for ssh

function autoCompleteHostname() { local hosts; local cur; hosts=($(awk '{print $1}' ~/.ssh/known_hosts | cut -d, -f1)); cur=${COMP_WORDS[COMP_CWORD]}; COMPREPLY=($(compgen -W '${hosts[@]}' -- $cur )) } complete -F autoCompleteHostname ssh
This is meant for the bash shell. Put this function in your .profile and you'll be able to use tab-completion for sshing any host which is in your known_hosts file. This assumes that your known_hosts file is located at ~/.ssh/known_hosts. The "complete" command should go on a separate line as such: function autoCompleteHostname() { local hosts=($(awk '{print $1}' ~/.ssh/known_hosts | cut -d, -f1)); local cur=${COMP_WORDS[COMP_CWORD]}; COMPREPLY=($(compgen -W '${hosts[@]}' -- $cur )) } complete -F autoCompleteHostname ssh

  • Downloads this raw script from Github, copies it to your home directory, autoloads it in ~/.bashrc and sources it.

    wget; mv git-completion.bash ~/.git-completion.bash; echo "source ~/.git-completion.bash" > ~/.bashrc; source ~/.git-completion.bash

  • In Bash, when defining an alias, one usually loses the completion related to the function used in that alias (that completion is usually defined in /etc/bash_completion using the complete builtin). It's easy to reuse the work done for that completion in order to have smart completion for our alias. That's what is done by this command line (that's only an example but it may be very easy to reuse). Note 1 : You can use given command line in a loop "for old in apt-get apt-cache" if you want to define aliases like that for many commands. Note 2 : You can put the output of the command directly in your .bashrc file (after the ". /etc/bash_completion") to always have the alias and its completion Show Sample Output

    old='apt-get'; new="su-${old}"; command="sudo ${old}"; alias "${new}=${command}"; $( complete | sed -n "s/${old}$/${new}/p" ); alias ${new}; complete -p ${new}

  • This is a multi-sourced hostname tab completion command you can put in your .bashrc (or your .bash_profile on a MAC). This will not only your .ssh/config, it will parse ALL of the following files for hostnames: .ssh/config .ssh/known_hosts .bash_history (I realize this could be prettied up by defining and calling the function, instead of implicitly referencing it, but this was more breif) Show Sample Output

    complete -W "$( { awk '/^Host / { print $2 }' ~/.ssh/config | egrep -v '\*|,' echo $( grep '^ssh ' .bash_history | sort -u | sed 's/^ssh //' ) while IFS=' ,' read host t; do echo $host; done < ~/.ssh/known_hosts ;} )" ssh

  • The really awesome bash completion in debian seems to be an extra package now, which has to be installed. After sourcing /etc/bash_completion it completes almost everything (package names in apt... etc) :-) To make this permanent, put something like this in your .bashrc: if [ -f /etc/bash_completion]; then source /etc/bash_completion fi

    aptitude install bash-completion ; source /etc/bash_completion
