Chè bà ba – Hình minh họa
Dự án phần mềm mã nguồn mở, miễn phí GNU coreutils cung cấp rất nhiều lệnh cho người dùng thao tác với hệ điều hành Linux bằng chế độ dòng lệnh (cli mode) hoặc viết bash script tự động.
Tự học Linux bằng 105 lệnh Linux có trong coreutils có cần thiết không? Cái này tùy thuộc vào bạn.
Hoặc bạn nên tham gia khóa học lập trình Bash shell chuyên sâu của chúng tôi để có lời khuyên từ những người đã làm việc với Linux 14+ năm.
Lệnh Linux là 1 bầu trời thương nhớ, không có đối thủ xứng tầm nếu so sánh với các lệnh quản lí router, switch của Cisco, Juniper…
