Debugging "exit status 1" Error in Golang Exec.Command

When utilizing exec.Command in Golang, encountering the enigmatic "exit status 1" error leaves one scratching their head for specifics. This article aims to illuminate this error's cause and provide a solution for more detailed diagnostics.

Consider the following code:

cmd := exec.Command("find", "/", "-maxdepth", "1", "-exec", "wc", "-c", "{}", "\")
var out bytes.Buffer
cmd.Stdout = &out
err := cmd.Run()
Copy after login

Executing this code results in the uninformative "exit status 1" error. To remedy this, leverage the Stderr property of the Command object:

var stderr bytes.Buffer
cmd.Stderr = &stderr
Copy after login

Upon executing, the error message will become apparent:

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

Now, equipped with this detailed error, you can address the issue accordingly.

Note: It's worth considering that some commands may redirect error messages to stdout rather than stderr. Additionally, certain commands may print error messages to stderr but still return a zero error code (leading to a nil err in your code). Therefore, it may be necessary to adjust the given solution to accommodate the specific commands you're using.
