In this tutorial, we’ll take a look at using user input as awhileloop condition in the Linux shell. 2. UnderstandingwhileLoops Before we dive into using user input, let’s first discuss the concept and syntax of awhileloop: while [condition]; do # Code block done Let’s break down ...
In Bash scripting, thewhileloop functions by repeating a set of instructions as long as the specified condition is true. Typically, the while loop is preferred where the number of iterations is uncertain or variable. In this guide, I will explore theBash while loop, its syntax, and usage th...

Bash Until Loop The until statement is very similar in syntax and function to the while statement. The only real difference between the two is that the until statement executes its code block while its conditional expression is false, and the while statement executes its code block while its co...
