`o [ ...]`

    The first URL to open in the web browser.

[ ...]
    Optional additional URLs to open. Each URL will typically be opened in a new tab or window, depending on the browser's configuration and how the `o` command is implemented.

The `o` command is a small, often custom-made, shell script or function designed to open URLs (Uniform Resource Locators) from the command line in a web browser. Its primary function is to provide a convenient shorthand for launching web pages directly from the terminal, improving workflow for developers and power users. Because `o` is not a standard Linux command, its implementation and functionality can vary widely depending on the system and the user who created it. Commonly, it uses environment variables (such as `$BROWSER`) or hardcoded browser paths to determine which browser to launch. It can also handle multiple URLs at once, opening each in a new tab or window. The scripts are often short and easily customizable.

The `o` command is not a standard Linux command. It is usually a custom script or function defined by the user or system administrator. Its functionality is therefore dependent on its specific implementation. Error handling might be limited or non-existent. Make sure the correct shell or terminal is setting the $BROWSER variable. Because this is user defined, it may not exist. If it exists there may not be any error handling if $BROWSER is not set or the set program is not a browser.

A simple implementation could be:
`o() { xdg-open "$@"; }` or
`o() { firefox "$@" & }`
or
`o() { google-chrome "$@" & }` These examples illustrate how the command can be implemented using other tools.
Another option is checking the environment variable `$BROWSER`

Users can modify the `o` command to suit their specific needs, such as adding support for specific URL patterns, or using different browsers based on command-line arguments.
They may also write `o` to accept only one url.

The `o` command, being a custom solution, lacks a formal history in the traditional sense. It likely emerged from the need for users to quickly open URLs from the command line, as a response to the inconvenience of manually copying and pasting URLs into a browser. Its development would typically involve shell scripting or function definition within a user's shell environment, with usage spreading through personal sharing and online forums.
