Ubuntu 的一些命令记录

1.更新软件源信息 apt-get update

该命令会访问源列表里的每个网址，并读取软件列表，然后保存在本地电脑。

注意：update是更新软件列表，upgrade是更新软件。 apt-get upgrade 会把本地已安装的软件，与刚下载的软件列表里对应软件进行对比，如果发现已安装的软件版本太低，就会提示你更新。

2.不支持netstat命令，安装net-tools

# apt-get install net-tools

root@7024be6158d7:/# netstat -tunlp
bash: netstat: command not found
