How Can I Execute Shell Scripts (.sh Files) Within Go Applications?

Utilizing Shell Scripts in Go: Executing .sh Files

When integrating shell scripts into Go applications, the task of executing an entire .sh file (complete with variable manipulations) can pose a challenge. Go's default os/exec package provides functionality for executing individual commands, but it lacks direct support for handling scripts.

To address this, you have two options:

Option 1: Preparing Your Script for Direct Execution

1. Begin your script with the shebang line, such as #!/bin/sh or #!/bin/bash.
2. Grant executable permissions to the script using chmod x script.sh.

Once you've made these adjustments, you can execute the script directly using exec.Command():

cmd := exec.Command("./script.sh")

Option 2: Executing with an Intermediate Shell

If you prefer not to modify your script, you can invoke the shell and pass the script as an argument:

cmd := exec.Command("/bin/sh", "mongoToCsvSH")

Remember, in this scenario, your script must reside within the system's $PATH environment variable or be provided as an absolute path.
