What's Next

  • The Generate command to generate a web player for a recording file.
  • Support apt-get, yum, brew installation.


Vous aurez besoin d'installer Node.js en premier, puis dans un terminal:

npm install -g git+

Still facing an issue? Check the Issues section or open a new issue.

The installation should be very smooth with Node.js v4-v16. For newer versions, if the installation is failed, you may need to install the development tools to build the C++ add-ons. Check node-gyp.

Identifiants NextCloud

Vous aurez besoin de renseigner dans le fichier de configuration vos identifiants NextCloud. Remplacer le username par votre nom d'utilisateur et le password par votre mot de passe.

  username: guillaume
  password: xxxxxxxxxx

Votre mot de passe ne sera pas partagé lors de la transmission du fichier d'enregistrement sur NextCloud

Getting Started

Start recording your terminal using the record command.

terminalizer record demo

A file called demo.yml will be created in the current directory. You can open it using any editor to edit the configurations and the recorded frames. You can replay your recording using the play command.

terminalizer play demo

Now let's render our recording as an animated gif.

The default config.yml file is stored under the root directory of the project. Execute the below command to copy it to your current directory.

Use any editor to edit the copied config.yml, then use the -c option to override the default one.

terminalizer config

RECOMMENDED, use the init command to create a global config file to be used instead of the default one.

For Linux and MacOS, the created directory is located under the home directory ~/.terminalizer. For Windows, it is located under the AppData.

  • cwd: Specify the current working directory path. The default is the current working directory path.

  • cols: Explicitly set the number of columns or use auto to take the current number of columns of your shell.
  • rows: Explicitly set the number of rows or use auto to take the current number of rows of your shell.


  • frameDelay: The delay between frames in ms. If the value is auto use the actual recording delays.
  • maxIdleTime: Maximum delay between frames in ms. Ignored if the frameDelay isn't set to auto. Set to auto to prevent limiting the max idle time.


  • quality: The quality of the generated GIF image (1 - 100).
  • repeat: Amount of times to repeat GIF:
    • If value is -1, play once.
    • If value is 0, loop indefinitely.

Frame Box

Terminalizer comes with predefined frames that you can use to make your GIF images look cool.

  • frameBox.title: To display a title for the frame or null.
  • To apply custom CSS styles or to override the current ones.

Null Frame

No frame, just your recording.

Don't forget to add a backgroundColor under style.

  type: null
  title: null
    backgroundColor: black

Window Frame

  type: window
  title: Terminalizer
  style: []

Floating Frame

  type: floating
  title: Terminalizer
  style: []

Solid Frame

  type: solid
  title: Terminalizer
  style: []

Solid Frame Without Title

  type: solid
  title: null
  style: []

Styling Hint

You can disable the default shadows and margins.

  type: solid
  title: null
    boxShadow: none
    margin: 0px


How to support ZSH

The default command that gets recorded for Linux is bash -l. You need to change the default command to zsh.

  • Generate a config file in the current directory
terminalizer config
  • Open the generated config file in your preferred editor.
  • Change the command to zsh:
command: zsh
  • You may need to change the font, check the font that is used in your terminal:
fontFamily: "Meslo for Powerline, Meslo LG M for Powerline"
  • Use the -c option to override the config file:
terminalizer record demo -c config.yml
