chage 『使用者在第一次登入時， 強制她們一定要更改密碼後才能夠使用系統資源』，可以利用如下的方法來處理的！
範例二：建立一個名為 agetest 的帳號，該帳號第一次登入後使用預設密碼，但必須要更改過密碼後， 使用新密碼才能夠登入系統使用 bash 環境[root@study ~]# useradd agetest[root@study ~]# echo "agetest" | passwd --stdin agetest[root@study ~]# chage -d 0 agetest[root@study ~]# chage -l agetest | head -n 3Last password change : password must be changedPassword expires : password must be changedPassword inactive : password must be changed# 此時此帳號的密碼建立時間會被改為 1970/1/1 ，所以會有問題！範例三：嘗試以 agetest 登入的情況You are required to change your password immediately (root enforced)WARNING: Your password has expired.You must change your password now and login again!Changing password for user agetest.Changing password for agetest(current) UNIX password: <==這個帳號被強制要求必須要改密碼！加密壓縮
