bash实现自动补全

yum install -y bash-completion

source /usr/share/bash-completion/bash_completion

执行后yum拥有选项自动补全功能

对于docker-compose还需要安装（docker不需要）：

curl -L https://raw.githubusercontent.com/docker/compose/1.22.0/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose

source  /etc/bash_completion.d/docker-compose

k8s中kubectl指令的补全

source  < (kubectl completion bash)

echo  "source  <(kubectl completion bash)"  >>  ~/.bashrc

git命令补全:

yum install  git-extras  gitflow  -y

source   /etc/bash_completion.d/*

或

wget  -O  /etc/bash_completion.d/git-completion.bash    https://raw.githubusercontent.com/markgandolfo/git-bash-completion/master/git-completion.bash

.   /etc/bash_completion.d/git-completion.bash
