(其實一共有3個問題,第一個問題在不久之前因為學長的好心幫忙完成了)
這一個問題阿~~導致我在即時更換使用者權限為root的時候被系統拒絕
[hentyduary@aabbcc ~]# su -
Password:
[hentyduary@aabbcc ~]# su: cannot set groups: Operation not permitted
......=.=|||
我就不得不直接切換使用者到root底下,在繼續用我要使用root處理的事情
抄凡的ㄟ
還好終於找到以下的解決方式:

ssh 问题请帮忙看一下!!!(很急)
環境,準備背景:
在台北市士林區的圖書館自修室最角落(背對人群面對牆壁,在牆角,對面沒有位置可讓別人坐,若你處的環境再對面有位置,你就想方法讓別人不想占那個位置)
準備期間:從11月到2月底(其實準備時間應該更長,但是非常確實的在準備的是這段時間)
帶耳塞,不聽音樂,手機調震動(本人的朋友較不常打電話過來,理當關機較好)
到圖書館只讀書和寫題目,不交談,不喵別人,不看報紙,不看閒書,不用電腦,不睡覺,...
6:30起床,吃早餐,洗澡(我比較習慣早上洗)
8:30圖書館開,占到位置之後隨即開始準備研究所的事務
12:00用餐到12:40後回到圖書館再讀
讀到17:00之後回到家(因為之後有許多高中生國中生會來,環境會比較吵)
17:00後小讀一下先小睡一下到19:00用晚餐
Hi,everyone:
Today, I learned many about some tools about Linux and blog. Although it is still in summer vacation, I think it is time to start my another more important jobs; I know it is not enough to learn only some elementary acknowledge about communication; I think I spent too little time to practice everything which the teacher gave me before.
I have learned about how to use shell script, but there are still some problem to solve, that is, I did not know how to use if...else: The original example of "if...else" is "if [ "$k" == "6" ]; then" when we want to say "if $k equal 6, and then .... But what about 'if $k bigger than 6' ? In the beginning, I knew that was "if [ "$k" > "6" ]; then", I tested it again and again, and at last I knew it was wrong.
This is my original code:
#!bin/bash
#this is my first homework in summer, 2008 in TONIC
#the target of this homework is how to use shell script
今天終於有進實驗室的感覺了,今天也在實驗室待了不短的時間
也終於見識到group meeting的陣仗了
話說昨天開始,我們實驗室已經為我們新生準備summer learning
昨天教授說明有關實驗室的規則,像是meeting之前要po blog
內容是有關要講的內容大綱,用英文撰寫
另外在meeting的時候,報告的同學也是要用英文來報告
而老師也希望同學有互動,所以也利用group meeting,來做議題的討論
而全程當然都是用英文來對話
對於英文,實在是因為底子實在是太差了,對於英文有說不出的恐懼
但由於(也可以說是幸虧)在實驗室之中有兩位外國人,
