您可以使用passwd收集一些信息,例如如果帳戶被鎖定

passwd -S user

user LK 2012-11-06 0 99999 7 -1 (Password locked.) (CentOS)

user L 01/22/2013 0 99999 7 -1 (Ubuntu)

chage實用程序將提供有關帳戶上各種計時器的信息,例如對于未過期的密碼

chage -l user

Last password change : Nov 12, 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

對于過期的密碼

chage -l user

Last password change : password must be changed

Password expires : password must be changed

Password inactive : password must be changed

Account expires : never

Minimum number of days between password change : 0

Maximum number of days between password change : 22

Number of days of warning before password expires : 33

passwd和chage實用程序還列出了許多帳戶鎖.

您可以使用getent直接從相關數據庫中提取信息進行檢查

getent passwd user

user:x:505:505::/home/passtest:/sbin/nologin

getent shadow user

user:!!:0:0:22:33:44::
