The `opera` command is used to start the Opera web browser from the command line. It allows users to open Opera with specific URLs, profiles, and configurations. While Opera is now based on Chromium, the command provides a consistent way to launch the browser, taking into account any custom installations or profiles the user may have. The command can be used in scripts or automated tasks to launch Opera, for example with a specific URL. It can also be useful in debugging or testing environments to quickly open Opera with a particular configuration.

The available options and their behavior might slightly vary depending on the specific Opera version installed. Some more advanced options might require specific configurations or environment variables. Check `opera --help` for a full list of supported options on your system.

The `opera` command typically returns an exit code of 0 upon successful launch. Non-zero exit codes might indicate errors during the launch process, such as invalid arguments or failure to start the browser.

Opera uses configuration files stored in the user's home directory to store settings, profiles, and extensions. While the `opera` command itself doesn't directly manipulate these files, understanding their location can be helpful for troubleshooting or customizing Opera's behavior. These configuration files store information about settings, extensions, and profiles.

Originally, Opera was a proprietary browser. The `opera` command has been available since the early releases. While the underlying engine changed from Presto to Chromium, the command's fundamental purpose remained: to launch the Opera browser from the command line. Over time new options were added and some deprecated.
