linux中给ssh命令加上自动完成功能

alias sshads='ssh -t -i /home/dong.guo/workspace/sshkeys/key_adsymp -l adsymp'
alias sshrootdraw='sshpass -p "drawbridge" ssh -l root'
alias sshrootkey='ssh -t -i /home/dong.guo/workspace/sshkeys/key_root -l root'
创建服务器列表文件，输入所有的服务器主机名
[dong.guo@heydevops ~]$ head -n 10 /home/dong.guo/workspace/autocomp/servers.list

# Enable auto-completion of servers via sshads, sshrootdraw and sshrootkey
function _servers() {
  COMPREPLY=()
  local cur=${COMP_WORDS[COMP_CWORD]};
  local com=${COMP_WORDS[COMP_CWORD-1]};
  case $com in
    'sshads')
      local servers=($(cat /home/dong.guo/workspace/autocomp/servers.list))
      COMPREPLY=($(compgen -W '${servers[@]}' -- $cur))
      ;;
    'sshrootdraw')
      local servers=($(cat /home/dong.guo/workspace/autocomp/servers.list))
      COMPREPLY=($(compgen -W '${servers[@]}' -- $cur))
      ;;
    'sshrootkey')
      local servers=($(cat /home/dong.guo/workspace/autocomp/servers.list))
      COMPREPLY=($(compgen -W '${servers[@]}' -- $cur))
      ;;
  esac
}

complete -F _servers sshads
complete -F _servers sshrootdraw
complete -F _servers sshrootkey
使配置生效
[dong.guo@heydevops ~]$ source .bashrc
