【ubuntu如何实现自动补齐】ubuntu实现自动补齐的方法:
1.以root权限利用vi编辑器打开/etc/bash.bashrc文件,命令:
sudovi/etc/bash.bashrc2.找到/etc/bash.bashrc文件中的下列代码进行修改 。


#enable bash completion in interactive shells
# if ! shopt -oq posix; then
# if [ -f /usr/share/bash-completion/bash_completion ]; then
# . /usr/share/bash-completion/bash_completion
# elif [ -f /etc/bash_completion ]; then
# . /etc/bash_completion
# fi
# fi


需要去掉去掉 if 到 fi 之间的注释 # 号,例如:


#enable bash completion in interactive shells
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi


3.最后刷新保存一下即可,命令:


source /etc/bash.bashrc
