linux - Linux 中的命令参数自动完成

Question

当我尝试以 root 用户 查看命令可用的参数时，我只看到目录:

.# 适合

.adobe/                          id_rsa                           .ssh/
.bash_history                    .local/                          

但是当我作为一个普通用户这样做时，我得到了参数列表:

.$ 适合

autoclean     clean         edit-sources  list          rdepends      showsrc       
autoremove    depends       full-upgrade  moo           remove        source.

有人请解释原因。

您应该尝试描述的内容 here

Check your /root/.bashrc file for these lines

if [ -f /etc/bash_completion ]; then
  . /etc/bash_completion
fi

If they do not exist add them to the end of the file using your favorite text editor.
