## Ejemplo
|
|
|
|
```go
|
|
conn := SSHConn{Host: "192.168.1.100", User: "deploy"}
|
|
stdout, stderr, code, err := SSHExec(conn, "df -h /")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
fmt.Printf("exit=%d\nstdout:\n%s\nstderr:\n%s\n", code, stdout, stderr)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Retorna stdout y stderr como strings separados mas el exit code. Si el comando remoto falla (exit code != 0), NO retorna error — el exit code indica el fallo. Solo retorna error si ssh no pudo conectar o ejecutar. Usa BatchMode=yes para evitar prompts interactivos.
