【Linux】使用useradd命令新建用户


如何新建用户

Linux下新建用户需要使用useraddpasswd命令

最基础的使用方法如下:

useradd  # 新建一个名为的用户
passwd   # 为该用户设定密码为

新建用户的最佳实践

不过作为服务器管理员,有时候我们需要连带着完成一些其他的目的
例如修改用户的默认shell(默认的/bin/sh功能太少,甚至不能使用方向键和Tab键)
以及为新用户指定home目录的位置

于是我们可以这么使用

useradd -d  -m -s /bin/bash 

对上述命令的翻译:
新建用户
-s:指定shell到/bin/bash
-d:指定其home目录为
-m:如果指定的home目录不存在,则新建

P.S. 对useradd命令的Usage翻译:
