Why Does My Go Code Keep Throwing 'Exit Status 1'?

How to Troubleshoot "Exit Status 1" Error in Golang's exec.Command

When utilizing exec.Command in Golang, you may encounter a non-specific "exit status 1" error that hinders debugging efforts. To obtain more detailed information:

Access the Command's Stderr Output

The Command object includes a Stderr property that captures error messages from the executed command. Modify your code to redirect stderr output to a variable:

var stderr bytes.Buffer
cmd.Stderr = &stderr

err := cmd.Run()
if err != nil {
    fmt.Println(fmt.Sprint(err) + ": " + stderr.String())
    return
}

Running this enhanced code will provide a more comprehensive error message, such as:

exit status 1: find: -exec: no terminating ";" or "+"

This clarifies that the error stems from an invalid command.

Handling Non-Standard Error Behavior

Note that some commands may deviate from the expected behavior of printing errors to stderr and returning a non-zero exit code. Certain commands, like ffmpeg, may print errors to stderr but return an exit code of 0. Additionally, some commands may print errors to stdout instead of stderr.

To accommodate these variations, you may need to adjust the code above to account for the specific commands you're using and the expected error handling pattern.
