EECS 280 Tutorials
macOS command line tools
macOS comes with a Terminal and can run UNIX command-line tools directly.
The macOS terminal command prompt ends with a $. To follow the steps below, type commands that appear after the $ and hit enter.
Open terminal
Open the Terminal application which comes with macOS.
Install compiler
Install a compiler.
$ xcode-select --install
Notice that this compiler is really Apple LLVM pretending to be g++. Your version might be different.
$ g++ --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 9.0.0 (clang-900.0.38)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Homebrew package manager
Install the Homebrew package manager.
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Apple Silicon users (“M1”, “M2”, etc.) only - Homebrew installs to a non-standard location, /opt/homebrew/. You’ll need to run the following to add Homebrew to your path:
$ echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile
Close your terminal and reopen your terminal.
Check your install. Your version might be different.
$ brew --version
Homebrew 4.3.18
Install CLI tools
Use the Homebrew package manager to install a few command line programs.
$ brew install wget git tree
Home Directory
Run cd ~. This will take you to your Ubuntu home directory. Running pwd afterward confirms the location. (Your username will be different.)
$ cd ~
$ pwd
/Users/jjuett
Create an EECS 280 folder by running mkdir ~/eecs280. Running ls afterward confirms the folder has been created.
$ mkdir ~/eecs280
$ ls
Desktop Downloads Movies Pictures eecs280
Documents Library Music Public
We highly recommend you store all coding work for EECS 280 projects and labs here.
Pitfall: Avoid paths that contain spaces. Spaces cause problems with some command line tools.
| Bad Example | Good Example |
|---|---|
EECS 280/ |
eecs280/ |
Project 1 Stats/ |
p1-stats/ |
Use CLI tools
Now would be a great time to take a look at our CLI Tutorial.
Pro-tips
CLI open file
Opens a file or directory with the default application, like a double click. See the open command in the CLI tutorial.
