在Ubuntu上經常會碰到程式無法關閉的情況，這時就需要強制把它殺死
首先使用ps -ef列出程序清單

到新公司後需要在Ubuntu12.04下搭建Android的開發環境，在這個過程中還是會碰到很多問題，在這裡記錄下來，友善自己以後和有需要的人參考。來源于網絡！
10、改變所屬的群組chown -R user1.user2 dir
如果目錄的群組所屬是root的話，在編譯一些檔案有可能會出錯，一般安裝時需要使用root，其它情況不建議使用sudo或root
修改前的D目錄是root使用者
使用指令
[email protected]:~$ sudo chown -R dzt.dzt D
修改後的群組所屬dzt，以上指令會周遊D目錄以下的所有目錄
檢視Linux系統資訊，Linux系統不像Window系統這麼友善，需要用到一些指令，在這裡收集了一些
1、檢視CPU的核數： cat /proc/cpuinfo | grep "cores" | uniq
2、檢視CPU的型号：cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
3、檢視記憶體總數：cat /proc/meminfo | grep MemTotal
檢視記憶體條數：dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range
檢視記憶體最大容量：dmidecode|grep -P 'Maximum\s+Capacity'
檢視記憶體頻率：dmidecode|grep -A16 "Memory Device"|grep Speed
4、檢視記憶體條型号：dmidecode -t memory
[email protected]:~$ sudo dmidecode -t memory

12、使用ssh遠端登入Linux系統
1.首先要安裝ssh
2.安裝後可以使用以下指令
[email protected]:~$ ssh [email protected]
登入使用者名為：dzt
IP位址為：18.8.6.87的伺服器或Linux系統
前提是要有密碼
遠端複制檔案
把dzt中的檔案VideoBackgroundController.java複制到deng使用者的根目錄
[email protected]:~$ scp -r [email protected]:dzt/VideoBackgroundController.java ~/
把deng的jackpal.androidterm_095443.apk複制到dzt的根目錄下dzt目錄
[email protected]:~$ scp -r jackpal.androidterm_095443.apk [email protected]:~/dzt
