asciinema

Asciinema is a popular command line tool used for recording and sharing terminal sessions. It allows users to capture their command line activities, including commands entered, output displayed, and even text-based user interfaces (TUI).

Here are some key features of asciinema:

1. Recording: Asciinema records the entire terminal session, capturing each keystroke and its output. It also records the timing and delay between actions, which creates a realistic playback experience for viewers.

2. Sharing: Once a session is recorded, asciinema generates a unique URL that can be shared with others. This allows users to easily showcase their work or problem-solving skills, especially in technical discussions or support forums.

3. Embedding: Asciinema provides an option to embed recordings on websites or in documentation. This is especially useful for tutorials, demos, or educational resources where it's helpful to visually demonstrate command line steps.

4. Playback: Recorded sessions can be played back using the asciinema player, which is available as a standalone tool or an HTML+JavaScript widget. The player offers playback controls like fast-forward, rewind, and pause, enhancing the viewing experience.

5. Collaboration: Asciinema provides features for multiple users to collaborate on a terminal session. It supports collaborative editing, real-time playback, and allows users to join, watch, or contribute to ongoing sessions.

6. Privacy: Asciinema respects user privacy by default. Only the user who recorded the session has access to the recording unless specifically shared.

Asciinema is an open-source tool available for various operating systems, including Linux, macOS, and Windows. It can be installed via package managers like pip (Python package manager) or Homebrew (for macOS).
