The loop structure is one of the key components of every programming language including Bash. They are used to repeat the specified instructions against a condition. Frequently employed loop structures in Bash scripting arefor,while, anddo-while. In Bash scripting, thewhileloop functions by repeatin...
The Bash while loop takes the following form: while [CONDITION] do [COMMANDS] done Copy The while statement starts with the while keyword, followed by the conditional expression.The condition is evaluated before executing the commands. If the condition evaluates to true, commands are executed. Oth...
Example-2: Using break statement for conditional exit the break statement is used to exit from the loop early based on a particular condition. Create a bash file named while2.sh with the following code. Here, the loop is defined to iterate 10 times, but the iteration will be stopped when...
This article has thoroughly explained all the Bash examples using the one-line while loop with different conditions. We have discussed the non-ending one-line loop and the conditional loop that can end on its own. Thus, we can say that our article contains quite diverse examples for our Linu...
How do I use while asinfinite loops? Infinite for while can be created with empty expressions, such as: #!/bin/bashwhile:doecho"infinite loops [ hit CTRL+C to stop]"done Conditional while loop exit with break statement You can do early exit with the break statement inside the whil loop...
InBashscripting, there are 3 types ofloops:for loop,while loop, anduntil loop. The three are used to iterate over a list of values and perform a given set of commands. In this guide, we will focus on theBash For Loopin Linux. ...
while : do echo "infinite loops [ hit CTRL+C to stop]" done 1. 2. 3. 4. 5. Conditional while loop exit with break statement You can do early exit with the break statement inside the whil loop. You can exit from within a WHILE using break. General break statement inside the while...
A while loop in bash consists of a conditional expression and a loop body which is surrounded by do and done. The loop body continues to be executed as long as the condition evaluates to true. The conditional expression in while loop can be surrounded by either a pair of single square ...
You can create an infinite While loop with the following command: You can use the built-in ":"or "true" commands that always returns “True” or any other conditional statement. Here’s the one-line expression: Example 2: a loop with a fixed number of repeats ...
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...
