This tutorial explains using the for loop in Bash scripts by using the range notation and the three-expression notation like in the C programming language.
For loop in Bash Script is used to execute specified statements/commands repeatedly. Bash For loop is similar to the loop inC language. If you are familiar with the C language then it is easy to understand the concept but if not then don't worry it is very simple to understand. Think l...

How to use a for loop in bash scripting? What are the basic syntax elements of a bash for loop? Can you provide an example of iterating through a list with a for loop in bash? This type of for loop is characterized by counting. The range is specified by a beginning (#1) and endin...
All three loops serve the same purpose of repeating the task N number of times when a condition is satisfied but with differences in how they are defined and used to achieve the result. This article will focus on"for loop" in Bash scripting. We will learn about the other two loops in ...
In the end, we will conclude by discussing the issue of the semi-colon;while making theforloop in the bash prompt. A loop in a programming or scripting language is an iterative control structure used to repetitively execute a statement or a set of statements until a certain criterion is not...
The ‘continue‘ statement is a built-in command that controls how a script runs. Apart from bash scripting, it is also used in programming languages such asPythonand Java. Thecontinue statementhalts the current iteration inside aloopwhen a specific condition is met, and then resumes the iterat...
