Could use your ssh bash history if your known_hosts are hashed and you want to keep it hashed

Alternatives

There are 8 alternatives - vote for the best!

Terminal - Alternatives
complete -W "$(echo $(grep '^ssh ' .bash_history | sort -u | sed 's/^ssh //'))" ssh

Stop tormenting the poor animal cat. See http://sial.org/howto/shell/useless-cat/.

Edit:

replaced

sort | uniq

by

sort -u
perl -ne 'print "$1 " if /^Host (.+)$/' ~/.ssh/config

I use this in my bashrc to expand hosts defined in ~/.ssh/config:

function _ssh_completion() {

perl -ne 'print "$1 " if /^Host (.+)$/' ~/.ssh/config

}

complete -W "$(_ssh_completion)" ssh

Here's a great article on how to setup your own ~/.ssh/config:

http://blogs.perl.org/users/smylers/2011/08/ssh-productivity-tips.html

complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ssh

Add to your bash profile to minimize carpal tunnel syndrome.

Doesn't work with user@hostname but appending "-l user" works fine if needed.

Works for ping as well..

complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping

complete -o default -o nospace -W "$(grep -i -e '^host ' ~/.ssh/config | awk '{print substr($0, index($0,$2))}' ORS=' ')" ssh scp sftp

I sue this in my .bashrc file

This will also do auto-completion for scp and sftp

complete -W "$(echo $(grep ^Host ~/.ssh/config | sed -e 's/Host //' | grep -v "\*"))" ssh

Autocomplete from .ssh/config

Know a better way?

If you can do better, submit your command here.

What others think

or you could set your hosts in .ssh/config

You just blew the purpose of a hashed known_hosts files with the history. It may protect you against bots, thats all.
