Memindahkan file yang relevan

Anda baru saja bergabung dengan sebuah startup baru sebagai salah satu dari sedikit karyawan teknis. Manajer Anda meminta bantuan untuk merapikan beberapa folder di server. Perusahaan telah mencoba berbagai perangkat lunak pemantauan server sehingga ada banyak file yang seharusnya dihapus.

Untungnya, Anda tahu bahwa semua file yang perlu dipertahankan mengandung vpt dan SRVM_ di suatu bagian isi file.

Tugas Anda adalah menulis skrip Bash yang akan menerima nama file sebagai elemen ARGV dan memindahkan file ke good_logs/ jika memenuhi kedua kondisi di atas. Ingat dari materi, flag q berarti 'quiet' sehingga tidak menampilkan baris yang cocok seperti biasanya grep. Flag ini hanya mengembalikan true jika ada baris yang cocok.

Ingat bahwa saat Anda menggunakan argumen baris perintah seperti grep di dalam pernyataan IF, tidak perlu tanda kurung siku, jadi jangan menambahkannya! Anda juga harus ingat untuk menjalankan skrip Anda dengan setiap file sebagai elemen ARGV. Satu per satu; total empat kali menjalankan skrip Anda.

Save yourself time when performing complex repetitive tasks. You’ll begin this course by refreshing your knowledge of common command-line programs and arguments before quickly moving into the world of Bash scripting. You’ll create simple command-line pipelines and then transform these into Bash scripts. You’ll then boost your skills and learn about standard streams and feeding arguments to your Bash scripts.

Exercise 1: Introduction and refresher Exercise 2: Extracting scores with shell Exercise 3: Searching a book with shell Exercise 4: Your first Bash script Exercise 5: A simple Bash script Exercise 6: Shell pipelines to Bash scripts Exercise 7: Extract and edit using Bash scripts Exercise 8: Standard streams & arguments Exercise 9: Using arguments in Bash scripts Exercise 10: Using arguments with HR data

Master the bread and butter of Bash scripts—variables! In this chapter, you’ll learn how to create basic string and numeric variables, and perform calculations on these variables. You’ll also learn about the magic of a shell-within-a-shell (shell-ception), opening up huge opportunities for advanced scripting.
