常用命令
To help us view and configure the status of SONiC, SONiC provides a large number of CLI commands for us to invoke. Most of these commands fall into two categories: show and config, and they are basically similar in format, most of them conform to the following format:
show <object> [options]
config <object> [options]
SONiC的文档提供了非常详细的命令列表：SONiC Command Line Interface Guide，但是由于其命令众多，不便于我们初期的学习和使用，所以列出了一些平时最常用的命令和解释，供大家参考。
SONiC中的所有命令的子命令都可以只打前三个字母，来帮助我们有效的节约输入命令的时间，比如：
show interface transceiver error-status
和下面这条命令是等价的：
show int tra err
为了帮助大家记忆和查找，下面的命令列表都用的全名，但是大家在实际使用的时候，可以大胆的使用缩写来减少工作量。
如果遇到不熟悉的命令，都可以通过输入-h或者--help来查看帮助信息，比如：
show -h
show interface --help
show interface transceiver --help
General
show version
show uptime
show platform summary
Config
sudo config reload
sudo config load_minigraph
sudo config save -y
Docker相关
docker ps
docker top <container_id>|<container_name>
如果我们想对所有的docker container进行某个操作，我们可以通过docker ps命令来获取所有的container id，然后pipe到tail -n +2来去掉第一行的标题，从而实现批量调用。
比如，我们可以通过如下命令来查看所有container中正在运行的所有线程：
$ for id in `docker ps | tail -n +2 | awk '{print $1}'`; do docker top $id; done
