Tôi không hiểu thông số của lệnh lsof.
Khi tôi viết
lsof -p PID
Tôi nhận được 4 dòng và khi tôi viết
lsof | grep PID
Tôi nhận được hàng trăm dòng.
Nó không nên trả lại kết quả tương tự?
Cám ơn bạn đã phản hồi của bạn. Đây là đầu ra. Có vẻ như đó là quá trình phụ hoặc nhiệm vụ này có ý nghĩa gì?
lsof -p 29076
