linux使用bash-completion補全【原創】

1、安裝

yum install bash-completion-1.3-7.el6.noarch.rpm

 

2、設置

重新登錄看是否生效，service + Tab看是否生效

# service

如果不生效可以使用以下方法

1）在用戶家目錄下

vi ~/.bashrc
. /etc/bash_completion

2）全局用戶生效

echo ". /etc/bash_completion" >> /etc/profile

 

echo ". /etc/bash_completion" >> /etc/profile
