Enable tab completion for known SSH hosts

complete -W "$(sed 's/;.*//;' /etc/hosts | awk ' /^[[:digit:]]/ {$1 = "";print tolower($0)}')" ssh

If you have a lot of hosts in /etc/hosts this would be very useful. Anyone have any more concise examples?

ssh autocomplete based on ~/.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

ssh autocomplete

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 Show Sample Output
