在Ubuntu上经常会碰到程序无法关闭的情况，这时就需要强制把它杀死

首先使用ps -ef列出进程列表

dzt@uu:~/workarea/8601_mp$ ps -ef

再使用kill pid来杀死对应的进程

到新公司后需要在Ubuntu12.04下搭建Android的开发环境，在这个过程中还是会碰到很多问题，在这里记录下来，方便自己以后和有需要的人参考。来源于网络！

10、改变所属的群组chown -R user1.user2 dir

如果目录的群组所属是root的话，在编译一些文件有可能会出错，一般安装时需要使用root，其它情况不建议使用sudo或root

修改前的D目录是root用户



使用命令

dzt@dzt-All-Series:~$ sudo chown -R dzt.dzt D

修改后的群组所属dzt，以上命令会遍历D目录以下的所有目录



查看Linux系统信息，Linux系统不像Window系统这么方便，需要用到一些命令，在这里收集了一些

1、查看CPU的核数： cat /proc/cpuinfo | grep "cores" | uniq



2、查看CPU的型号：cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c



3、查看内存总数：cat /proc/meminfo | grep MemTotal



查看内存条数：dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range



查看内存最大容量：dmidecode|grep -P 'Maximum\s+Capacity'



查看内存频率：dmidecode|grep -A16 "Memory Device"|grep Speed



4、查看内存条型号：dmidecode -t memory

dzt@dzt-All-Series:~$ sudo dmidecode -t memory
# dmidecode 2.11
SMBIOS 2.7 present.

12、使用ssh远程登录Linux系统

1.首先要安装ssh

2.安装后可以使用以下命令

deng@deng-All-Series:~$ ssh dzt@18.8.6.87

登录用户名为：dzt

IP地址为：18.8.6.87的服务器或Linux系统

前提是要有密码

远程复制文件

把dzt中的文件VideoBackgroundController.java复制到deng用户的根目录

deng@deng-All-Series:~$ scp -r dzt@18.8.6.87:dzt/VideoBackgroundController.java ~/

把deng的jackpal.androidterm_095443.apk复制到dzt的根目录下dzt目录

deng@deng-All-Series:~$ scp -r jackpal.androidterm_095443.apk dzt@18.8.6.87:~/dzt
