Then load that file: in your ~/.bash_profile, add:

. /etc/bash_completion.d/ssh

config别名列表

if you want to see a list of all your hosts, you can add this alias to your .bash_profile:

# list all "Host" and "HostName" lines, then remove the strings: "Host " and "HostName "
alias sshhosts="grep -w -i -E 'Host|HostName' ~/.ssh/config | sed 's/Host //' | sed 's/HostName //'"
