Cursor AI IDE Installer and Updater Script

Description:

This script installs or updates the Cursor AI IDE on Linux systems. It downloads the AppImage, sets up an application menu entry, and adds a shell alias (cursor) for easy usage. The script supports multiple shells (bash, zsh, fish) and gracefully handles updates.

Features:

• Downloads and installs the Cursor AI IDE AppImage and icon.
• Adds a .desktop entry for the system's application menu.
• Configures an alias for quick access (cursor).
• Automatically detects the user's shell and modifies the appropriate configuration file.
• Allows overwriting the existing installation for updates.

Prerequisites:

• Some users have reported crashes due to compatibility issues with other versions of libfuse. To prevent this, ensure you have libfuse2 installed by running:

  sudo apt install libfuse2

Instructions:

1. Copy the script into a file, e.g., install_cursor.sh.

   curl https://gist.githubusercontent.com/Kinyugo/9845e18998744ff54b8f0cde3bb37182/raw/a9425582958c14f80acea08e51c49b1bf63840c7/install_cursor.sh

   or

   wget https://gist.githubusercontent.com/Kinyugo/9845e18998744ff54b8f0cde3bb37182/raw/a9425582958c14f80acea08e51c49b1bf63840c7/install_cursor.sh

2. Make the script executable:

   chmod +x install_cursor.sh

3. Run the script

   ./install_cursor.sh

4. Restart your terminal or run the following command:

   source /path/to/terminal/config

Thank you @Kinyugo but this script didn't help me much
After running the script, it has just installed the version 0.45 of cursor while the v.48 is already out. I don't know what went wrong, I need some help to upgrade my Cursor.

Hiya @odilson-dev -- it's not the script that's not working, it's something with the Cursor "latest" link (https://downloader.cursor.sh/linux/appImage/x64). For some reason, even though newer versions have been released, this link consistently pulls down 0.45.

This repo keeps an up-to-date list of the latest Cursor releases. If you replace the CURSOR_URL var in this script with the latest Linux link (or whatever version you'd like) in the script, you'll be in business.

In my fork of this script, I've added a prompt to replace the default URL with another for ease of use, with a fallback to the existing "latest" URL if none is provided.
