EXPIRE=

Example 7: specify parameters to execute useradd-D-e

[root@oldboy ~] # date +% F

2012-01-25

[root@oldboy ~] # useradd-D-e 01Universe 19 # → modifies the default new account expiration time, after which all new users will expire.

[root@oldboy ~] # useradd-D | grep EXPIR # → modification has been effective.

EXPIRE=01/19/12

[root@oldboy ~] # useradd tmpuser3 # → add user tmpuser3. Note that the-e parameter is not added.

The minimum number of days between two password changes: 0

The maximum number of days between two password changes: 99999

[root@oldboy ~] # useradd-D-e "" # → restore after testing

[root@oldboy] # useradd-D

GROUP=100

HOME=/home

INACTIVE=-1

EXPIRE= # → restored

SHELL=/bin/bash

SKEL=/etc/skel

CREATE_MAIL_SPOOL=yes

Special note: only the default value of the configuration file has been changed, and it only takes effect for new users who are established later, not for old users.

When changing a user:

Method 2: modify the account attribute usermod-e 01qq28x12 oldboy

Method 3: adjust account expiration chage-E 01max 28x12 oldboy

View account expiration: chage-l oldboy

The configuration can be scripted by passing a time parameter at each stage.
