Control Structures and Logical Operators in Shell Scripting
This lesson teaches you how to use control structures and logical operators in shell scripting. You'll learn how to make decisions within your scripts using `if-else` statements and combine multiple conditions with `&&` (AND) and `||` (OR) operators.
Shell Scripting Part 3: Decision Control Structures in Shell Scripts
This part of our shell scripting tutorials will show you how to use shell scripting for condition based decision making. Just like in a programming language but this time using bash shell.
Shell programming with bash: by example, by counter-example
Control structures. Like most languages, bash supports control structures for conditionals, iteration and subroutines. Conditionals. If-then-else-style conditionals exist in bash, as in other languages. However, in bash the condition is a command, and an exit status of success (0) is "true," while an exit status of fail (non-zero) is "false.":
Shell Script Control Structures • Control structures allow commands in a script to be executed in a different order • Without control structures, a shell script could only ostart at the beginning... o...and go to the end once which would limit what it could do • There are two basic types of control structures oConditionals (Branching ...

Mastering Conditional Logic in Shell Scripts: Control Execution …
Introduction to Conditional Logic in Shell Scripting. In the world of shell scripting, conditional logic is your control tower — it helps you guide your script’s behavior based on real-time decisions. Whether you’re automating a CI/CD pipeline or simulating a rocket launch (as we do in this tutorial), understanding conditional logic is essential to building intelligent, robust scripts.
