Introduction<\/h2>\n

chage is short for “Change Age”, which is used to view and edit password change time information, setting account status, change the expiry date of the account.<\/p>\n

We must change password information regularly to ensure security, especially for administrators.<\/p>\n

In this article, we will show you how to use the chage command in Linux in detail along with examples.<\/p>\n

The syntax of chage command<\/h2>\n
$ chage [options] LOGIN<\/pre>\n
[options]<\/strong><\/p>\n
-l <\/strong> display the expiry information<\/p>\n
For example, I want to check the expiry information of \u201cubuntu\u201d:<\/p>\n
$ chage -l ubuntu<\/pre>\n
Output:<\/p>\n
<\/p>\n
-d<\/strong> change the expiry information<\/p>\n
Now I want to specify the expiration date of \u201cubuntu\u201d as of June 30, 2021:<\/p>\n
$ sudo chage -d 2021-06-30 ubuntu<\/pre>\n
Then use chage command with -l <\/strong>option to check:<\/p>\n

<\/p>\n
The expiry date has changed.<\/p>\n
-E <\/strong> lock the account<\/p>\n

Then use chage command with -l <\/strong>option to check:<\/p>\n
$ chage -l ubuntu<\/pre>\n
<\/p>\n
As you can see, my account will be locked on Jun 30, 2023.<\/p>\n
-M<\/strong> set maximum time before the password can be changed.<\/p>\n
I want to set the value as 365:<\/p>\n
$ sudo chage -M 365 ubuntu<\/pre>\n
Then use chage command with -l <\/strong>option to check:<\/p>\n
$ chage -l ubuntu<\/pre>\n
