Hi
from shadow man page:
NAME
shadow - encrypted password file
DESCRIPTION
shadow contains the encrypted password information for user's
accounts and optional the
password aging information. Included is
Login name
Encrypted password
Days since Jan 1, 1970 that password was last changed
Days before password may be changed
Days after which password must be changed
Days before password is to expire that user is warned
Days after password expires that account is disabled
Days since Jan 1, 1970 that account is disabled
A reserved field
-------------------------------------------------------
I guess you can get it with 'cut' command. something like:
TIME=`grep <username> /etc/shadow | cut -d":" -f 5`
echo "your password will expire in $TIME days"
the problem is that you can run this commands only as root (users don't have
read permissions on shadow file), so you can redirect it to their mails.
Bye
