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.

Script Bash pertama Anda

#!/bin/bash

# Concatenate the file
____ ____.txt



#!/bin/bash

# Concatenate the file
cat server_log_with_todays_date.txt



Skrip Bash sederhana

#!/bin/bash

# Create a single-line pipe
cat ____.csv | cut -d "____" -f ____ | tail -n +2 | sort | ____ -c

# Now save and run!


#!/bin/bash

# Create a single-line pipe
cat soccer_scores.csv | cut -d "," -f 2 | tail -n +2 | sort | uniq -c

# Now save and run!


Dari pipeline Shell ke skrip Bash

#!/bin/bash

# Create a sed pipe to a new file
cat ____.csv | sed 's/____/____/g' | sed '____' ____ soccer_scores_edited.csv

# Now save and run!


#!/bin/bash

# Create a sed pipe to a new file
cat soccer_scores.csv | sed 's/Cherno/Cherno City/g' | sed 's/Arda/Arda United/g' > soccer_scores_edited.csv

# Now save and run!

From Command-Line to Bash Script

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.

Life isn't always linear and neither should your Bash scripts. In this chapter, you’ll take your Bash scripts to the next level by learning control statements. You’ll learn the differences between FOR, WHILE, IF, and CASE statements and how to use them in your Bash scripts. Armed with these new tools, you’ll be ready to create more advanced Bash scripts with conditional logic. 

IF statements

Sorting model results

Moving relevant files

FOR loops & WHILE statements

A simple FOR loop

Correcting a WHILE statement

Cleaning up a directory

CASE statements

Give your Bash scripts a powerful new addition by building useful functions to process data and variables. In this last chapter, you will learn the structure of functions in Bash, how to use functions to help automate frequent tasks, and program your scripts to run on schedule without needing to even lift a finger.

Basic functions in Bash

Uploading model results to the cloud

Get the current day

Arguments, return values, and scope

A percentage calculator

Sports analytics function

Bash adalah bahasa scripting yang ringkas, sangat cepat, dan andal untuk manipulasi data serta berkas. Ini merupakan keterampilan penting untuk membangun pipeline analitik di cloud, dan menjadi pilihan para pengguna Linux untuk mengelola data yang tersimpan di berbagai berkas.

Dalam kursus ini, kami akan memandu Anda melalui dasar-dasar Bash scripting. Kita mulai dengan pengenalan struktur skrip Bash, termasuk memasukkan argumen dan menghasilkan keluaran. Anda kemudian akan mempelajari struktur data seperti variabel dan array, serta pernyataan kendali seperti loop dan kondisional. Selanjutnya, Anda akan mempraktikkan yang telah dipelajari dengan membuat fungsi Bash Anda sendiri dan menjadwalkan skrip otomatis agar berjalan tepat waktu dengan cron.
