/etc/shadow files stores actual password in encrypted format for user’s account. How do I check users password expiry information under Linux operating systems?
You need to use the chage command. It can display password expiry information as well as changes the number of days between password changes and the date of the last password change. This information is used by the system to determine when a user must change his/her password.
View account again information:
To see account aging information such as expiry date and time, enter:
chage -l userNameHere |
To see account aging info for vivek, enter:
$ chage -l vivek
Sample outputs:
Last password change : Jan 10, 2012 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7
Another example:
$ chage -l raj
Sample outputs:
Last password change : May 21, 2012 Password expires : Jun 20, 2012 Password inactive : never Account expires : Jan 01, 2013 Minimum number of days between password change : 7 Maximum number of days between password change : 30 Number of days of warning before password expires : 7

Is there a way to list just the expiration date ? (or any of the other specific fields reported by chage ?)
Really? just grep it or awk with a pipe… easy enough
Is it possible to get the time in addition to the date. On AIX, the password expiration warning includes the date and time. My password will expire tomorrow. It would be helpful to know what time it will expire so that I can determine how much time I’ll have tomorrow before it expires? If it’s going to expire early in the day, I may want to change it today. If it expires late in the day I may wait until tomorrow morning.
Thanks.

I have the same question as Jerry. Is it possible to know the last password change time in Linux?
chage -l root | grep “Last password change” | awk -F”:” ‘{print $2}’
Hi!, i need known the expiration date of the all user with one script, it´s possible?
for account in $(cut -f1 -d: /etc/passwd); do echo "ACCOUNT: $account , EXPIRES: `chage -l $account | grep 'Account expires' | awk '{print $4, $5, $6}'`, CHANGED: `chage -l $account | grep 'Last password change' | awk '{print $5, $6, $7}'`"; doneHow do we check the same info when the linux server is connected to Active Directory and there is no value in /etc/passwd?
