使用 chage 更新 linux 用户密码过期时间

            chage,其实很好记,就是 change age。主要用于更新和 linux 用户相关的各种过期信息,比如 账号过期时间密码过期时间等,具体参数如下:
[root@VM_61_237_centos ~]# chage --help
Usage: chage [options] LOGIN

Options:
  -d, --lastday LAST_DAY        set date of last password change to LAST_DAY
  -E, --expiredate EXPIRE_DATE  set account expiration date to EXPIRE_DATE
  -h, --help                    display this help message and exit
  -I, --inactive INACTIVE       set password inactive after expiration
                                to INACTIVE
  -l, --list                    show account aging information
  -m, --mindays MIN_DAYS        set minimum number of days before password
                                change to MIN_DAYS
  -M, --maxdays MAX_DAYS        set maximim number of days before password
                                change to MAX_DAYS
  -R, --root CHROOT_DIR         directory to chroot into
  -W, --warndays WARN_DAYS      set expiration warning days to WARN_DAYS

[root@VM_61_237_centos ~]# 

其中 -l 选项可以查看用户当前的过期信息:

[root@VM_61_237_centos ~]# chage -l root
Last password change                                    : Jun 08, 2018

Account expires                                         : never
Minimum number of days between password change          : 0
Maximum number of days between password change          : 99999

[root@VM_61_237_centos ~]# 

和命令参数的对比之下,那个参数有什么用就一目了然了。
