Install Python 3.x using your preferred package manager.

Install the requests package with pip install requests. Depending on your distribution, the command may be pip3 rather than just pip. To find out which command is the right one, run pip --version and pip3 --version and check the outputs.

This program needs Streamlink to be installed somewhere in your $PATH in order to open livestreams in a video player. You can follow the installations instructions on the Streamlink GitHub page.

Download twitch-cli.py and place it in any directory. To run the program, run python3 /path/to/twitch-cli.py.

You can also move twitch-cli.py to a directory in your $PATH (/usr/local/bin/ or $HOME/bin/), rename it to twitch-cli (or anything you want) without a file extension and make it executable. That way, you can simply run the command twitch-cli from the terminal.

Download and install Python 3.x from the Python website.

Install the requests package with pip install requests.

This program needs Streamlink to be installed somewhere in your %PATH% in order to open livestreams in a video player. You can follow the installations instructions on the Streamlink GitHub page.

Download twitch-cli.py and place it in any directory. To run the program, open a command line and run python3 X:\path\to\twitch-cli.py.

To make the command twitch-cli available, follow these steps:

1. Go to C:\Users\YOURUSERNAME\AppData\Roaming\twitch-cli\ (create the directory if it doesn't exist yet)
2. Place the file twitch-cli.py in there
3. Create a new text file called twitch-cli.bat
4. Open it, paste the following code, save and close

@echo off
SET cwd=%~dp0
python "%cwd%\twitch-cli.py" %*

5. Go to the environment variable dialog (not explained here) and edit the Path variable of your user account. Adda new line with the content "%APPDATA%\twitch-cli" and hit OK.

You can now open a command line and run twitch-cli anywhere.

You can authenticate with Twitch using python3 twitch-cli.py auth. Follow the instructions and copy the OAuth key into the application or the configuration file.

After executing the script for the first time, you will find a configuration file at:

• GNU/Linux: $HOME/.config/twitch-cli/config.json
• Windows: %APPDATA%/twitch-cli/config.json

Everything you can configure will have a default value in the configuration file. There are no hidden options. If you want to reset an option to its default, delete it from the file and it will get reset the next time you run the program.
