macOS is a Unix, and not built on Linux.

I think most of us realize that macOS isn't a Linux OS, but what that also means is that instead of shipping with the GNU flavor of command line tools, it ships with the FreeBSD flavor. As such, writing shell scripts which can work across both platforms can sometimes be challenging.

Homebrew

Homebrew can be used to install the GNU versions of tools onto your Mac, but they are all prefixed with "g" by default.

All commands have been installed with the prefix "g". If you need to use these commands with their normal names, you can add a "gnubin" directory to your PATH from your bashrc.

2. Launch Xquartz. Go to Preference -> Security, click the box Allow connections from clients. NOTE: You have to lauch Xquartz with Allow connections from clients enable everytime you want to ssh to remote server with X11 forwarding support.

环境：shadowsocks、windows
本地ss端口设置(这里1080)

cmd命令行:(不用socks5)(临时设置)(也可放置环境变量)
set http_proxy=http://127.0.0.1:1080
set https_proxy=http://127.0.0.1:1080

ps:一定要用cmd命令行，千万别用powershell !!!
简易测试命令：curl https://www.google.com（别用ping）

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start
