解决linux终端按tab不能自动补全的问题

刚装了个pearos发现终端里按tab键无法自动补全

解决方法如下，打开/etc/bash.bashrc

将以下几行的注释取消，取消后如下

# 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

再重启终端即可
