While logging into one of the Linux jump boxes at work today, it occurred to me that while I recently got notified about my password expiration from our Active Directory farm, I had no idea when my Linux password would expire or what the password life was.
To find out this information you can easily use the chage command.
Here is what the output looks like:
[code language=”bash”][[email protected] ~]$ chage -l user
Last password change : Apr 09, 2015
Password expires : Jul 08, 2015
Password inactive : never
Account expires : never
Minimum number of days between password change : 1
Maximum number of days between password change : 90
Number of days of warning before password expires : 7
It may seem like such a simple thing to do, but knowing when your password expires can be a lifesaver on occasion.
