You need to be root to do this but there is no single command available. From the /etc/security/passwd you get the information when the password for a particular user was set ("lastupdate"). You'd then check the user's attributes to find the intervall for a forced password change. With those two values and the current date you can calculate when the current password will be expired. Thus a script would probably be written around the following commands:
Search the script forum to find how to convert a date into seconds from epoch for easy comparison. You might even find several complete scripts there for accomplishing your aim.
Hi,
Is there any way of sending an email to a number of users indicating that the passwords of user accounts will expire?
Currently we have a test server with a number of oracle test accounts on it. Each of these accounts correspond to an instance of Oracle on the server. These... (2 Replies)

pam_pwcheck - PAM module for password strength checking
DESCRIPTION
The pam_pwcheck is a PAM module for password strength checking. It makes additional checks upon password changes, but does not perform the
change itself. It only provides functionality for one PAM management group: password changing.
This module works in the following manner: if enabled, it first calls the Cracklib routine to check the strength of the password; if crack
likes the password, the module does an additional set of strength checks. These checks are:
Palindrome
Is the new password a palindrome of the old one?
Case Change Only
Is the new password the old one with only a change of case?
Similar
Is the new password too similar to old one?
Simple Is the new password too short?
Rotated
Is the new password a rotated version of the old password?
Already used
Was the password used in the past? Previously used passwords are to be found in /etc/security/opasswd.
OPTIONS
The following options may be passed to the module:
cracklib=<path to dictionaries>
Use cracklib library for password checks. This parameter also contains the path to the cracklib dictionaries. The default is
/usr/lib/cracklib_dict.
debug A lot of debug information is printed with syslog(3).
maxlen=number
Number of significant characters in the password for crypt(3). A value of zero suppresses this check. The default is 0.
minlen=number
The minimum number of characters in an acceptable password. A new password with fewer characters will be rejected. A value of zero
suppresses this check. The default is 5.
no_obscure_checks
No additional checks will be performed before a new password is accepted. Since the checks performed are fairly simple, their usage
is recommended.
not_set_pass
If this option is given, pam_pwcheck will not make the new password available for other modules.
nullok Normally the account is disabled if no password is set or if the length of the password is zero. With this option you can allow the
user to change his password for such accounts. This option does not overwrite a hardcoded default by the calling process.
tries=number
Maximum number of attempts to change a password if the new ones are rejected because they are too easy.
use_authtok
Set the new password to the one provided by the previously stacked password module. If this option is not set, pam_pwcheck will ask
the user for the new password.
use_first_pass
By default pam_pwcheck tries to get the authentication token from a previous module. If no token is available, the user is asked
for the old password. With this option, pam_pwcheck aborts with an error if no authentication token from a previous module is
available.
remember=XX
Remember the last XX passwords and do not allow the user to reuse any of these for the next XX password changes. XX is a number
between 1 and 400.
enforce_for_root
If this option is set, most of the password check rules are enforced for root, too. Never use this option if you don't know what
you are doing, since it could be as result that root is no longer allowed to login at all.
