Overview/Description
Bash syntax is a scripting language used for data manipulation. During this course, you will learn how to form conditional statements and evaluate them with the Bash test command tool. Begin by creating compound conditional statements with comparison operators. Next, learn how to use a for loop construct within a Shell script. Other topics include wildcards, while loops, until loops, break and continue commands, and case statements. From there you will observe how to create an array, and manipulate data. Then discover how to perform simple math operations, calculate floating point math, and convert numbers between bases. Conclude by employing Bash's string manipulation operations and learn the basic syntax to manipulate strings, directories, and directory structures.

Target Audience
System administrators, DevOPS, software developers, and users who may need to create scripts to automate processes in a Linux or Linux-like environment
