Bash Scripting Flow Control and Data Types from Skillsoft

Online, Self-Paced

In this course, you will learn how to control the flow inside a Bash script using conditions and loops. You will also learn about some of the advanced features and capabilities of strings, numbers, and arrays.

Learning Objectives

Flow Control

start the course
work with conditional statements in Bash scripts and use the built-in test command to evaluate expressions
recognize numeric, string, and test comparison operators and create compound conditional statements
work with for loops and wildcards
use while and until loops to iterate through a list or run until a condition is achieved
use break and continue to control the iterations of a loop
create a case statement and use it in place of a nested if statement

Arrays, Strings, and Numbers

create an array by adding and removing elements and manipulate the data in the array
perform simple math operations in a Bash script and use the bc utility to do floating point math
create and use a Bash script to convert numbers between different bases
manipulate strings using the built-in Bash string manipulation operations
use popd, pushd, dirs, pwd, cd, and $DIRSTACK to work with directories and directory structures in a Bash script

Practice: Conditionals and Data Types

work with conditional statements, loops, and arrays in Bash scripts and manipulate string and numeric data
