CentOS bash命令自动补齐功能

1.安装 bash-completion

• yum install bash-completion
• 无法安装需要添加epel源
  • centos 6
    rpm -ivh http://mirrors.sohu.com/fedora-epel/6/i386/epel-release-6-8.noarch.rpm
  • centos 5
    rpm -ivh http://mirrors.opencas.cn/epel/5/i386/epel-release-5-4.noarch.rpm

2.使用前执行以下命令中的一条，或者重连服务器即可

• . /etc/bash_completion
• source /etc/bash_completion

3. 测试
