如果要针对用户帐户运行pwdadm -c并清除/ etc / passwd中的标志， 那些清除的标志停止发生什么？
根据手册页，这里是pwdadm -c可能删除的标志：
NOCHECK Signifies that new passwords need not follow the guidelines established in the /etc/security/user file for password composition. ADMIN Specifies that password information may be changed only by the root user. Only the root user can enable or disable this attribute. ADMCHG Resets the ADMCHG attribute without changing the user's password. This forces the user to change passwords the next time a login command or an su command is given for the user. The attribute is cleared when the user specified by the User parameter resets the password.
