Find Chrome Executable Path in Go on macOS

To find the path of the Chrome executable in Go on macOS, you can use the exec.Command function from the os/exec package to execute a shell command that retrieves the path. Here are the steps:

1. Import the necessary packages:

import (
    "os/exec"
    "log"
)

1. Use the exec.Command function to execute the shell command which google-chrome:

cmd := exec.Command("which", "google-chrome")

1. Execute the command and capture the output:

output, err := cmd.Output()
if err != nil {
    log.Fatal(err)
}

1. Convert the output to a string and trim any leading or trailing whitespace:

chromePath := strings.TrimSpace(string(output))

Explanation of each step: 1. Importing necessary packages: The os/exec package provides functions for executing shell commands, and the log package is used to handle errors. 2. Executing the shell command: The exec.Command function creates a new Cmd struct with the specified command and arguments. 3. Capturing the output: The Output method of the Cmd struct executes the command and captures its output. 4. Converting and trimming the output: The captured output is converted to a string and any leading or trailing whitespace is removed using the strings.TrimSpace function.

By following these steps, you will be able to retrieve the path of the Chrome executable in a Go program running on macOS.
