新建用户test
[root@86 ~]# useradd test [root@86 ~]# passwd test Changing password for user test. New password: BAD PASSWORD: it is too simplistic/systematic BAD PASSWORD: is too simple Retype new password: passwd: all authentication tokens updated successfully. [root@86 ~]# id test uid=505(test) gid=505(test) groups=505(test) [root@86 ~]# usermod -d /tmp/ test [root@86 ~]# su - test -bash-4.1$ pwd /tmp/
但usermod命令对root没有用,只能对普通用户。对root来说应该只有一种方法，就是直接修改/etc/passwd
