NAME
       chage - change user password expiry information

SYNOPSIS
       chage [-D binddn] [-P path] [-m mindays]
	     [-M maxdays] [-d lastday] [-I inactive] [-E expiredate] [-W warn‐
	     days] user

       chage -l [user]

DESCRIPTION
       chage is used to list and change the password expiry information	 of  a
       user.  It  allows the system administrator to change the number of days
       between allowed and required password changes and the date of the  last
       password	 change. It allows also to define when an account will expire.
       The chage command is restricted to the system administrator, except for
       the -l option, which may be used by an user to determine when his pass‐
       word or account is due to expire.

       If no option is given, chage operates in an interactive mode, prompting
       the  user  with the current values for all of the fields. Enter the new
       value to change the field, or leave the line blank to use the   current
       value.  If  the	users  exists in the local passwd file, but not in the
       local shadow file, chage will create a new entry in the shadow file.

OPTIONS
       -D, --binddn binddn
	      Use the Distinguished Name binddn to bind to the LDAP directory.
	      The  user will be prompted for a password for simple authentica‐
	      tion.

       -P, --path path
	      The passwd and shadow files  are	located	 below	the  specified
	      directory	 path.	chage will use this files, not /etc/passwd and
	      /etc/shadow.  This is useful for example on NIS master  servers,
	      where  you  do  not  want	 to give all users in the NIS database
	      automatic access to your NIS server and the  NIS	map  is	 build
	      from special files.

       -l, --list
	      This option will list the password expiry information in a human
	      readable format. The user will see the date when he changed  the
	      password	the  last time, when the password will be expire, when
	      the password will be locked and when the account will expire.

       -m, --mindays mindays
	      With this option the minimum number  of  days  between  password
	      changes  is  changed.  A	value of zero for this field indicates
	      that the user may change her password at any time. Else the user
	      will not be permitted to change the password until min days have
	      elapsed.

       -M, --maxdays maxdays
	      With this option the maximum number of days during which a pass‐
	      word is valid is changed. When maxdays plus lastday is less than
	      the current day, the user will be required to change  his	 pass‐
	      word before being able to use the account.

       -d, --lastday lastday
	      With this option the date when the password was last changed can
	      be set to another value. lastday has to be specified  as	number
	      of  days since January 1st, 1970. The date may also be expressed
	      in the format YYYY-MM-DD. If supported by the system, a value of
	      zero forces the user to change the password at next login.

       -E, --expiredate expiredate
	      With  this  option the date when the account will be expired can
	      be changed. expiredate has to be specified  as  number  of  days
	      since  January  1st, 1970. The date may also be expressed in the
	      format YYYY-MM-DD.

       -I, --inactive inactive
	      This option is used to set the  number  of  days	of  inactivity
	      after  a	password  has  expired before the account is locked. A
	      user whose account is locked must contact the  system   adminis‐
	      trator  before  being able to use the account again.  A value of
	      -1 disables this feature.

       -W, --warndays warndays
	      With this option the number of days of warning before a password
	      change  is required can be changed. This option is the number of
	      days prior to the password expiring that a user will  be	warned
	      the password is about to expire.
