Thecontinuecommand ends the current loop iteration. The program continues the loop, starting with the following iteration. To illustrate, add the following code to a Bash script to see how thecontinuestatement works in aforloop: #!/bin/bash # For loop with continue statement for i in {1.....
The scripts below demonstrate using the for loop in Bash scripts. This script sets the value of the variableito1the first time, and it printsline number 1. Then it goes back to theforloop, sets variableito2, and printsline number 2. ...
The Bash script provides two syntaxes for writing theforloops. The first one is known as C-style or three expression loop, and it is nearly the same as the C-language formulation for theforloop. The second formulation is a famousforeachorfor-instyle construct, also have been adopted by ...
Bash Copy In this example, we’ve created a ‘for’ loop that acts as a ‘foreach’ loop. The loop iterates over the numbers 1 through 5, echoing each number on a new line. This is a basic way to use the ‘foreach’ loop in Bash, but there’s much more to learn about loopin...

Loops are used in any programming language to execute the same code repeatedly. Three types of loops are mainly used in programming for doing repetitive tasks. These are for, while, and do-while/repeat-until loop. You can apply for loop on bash script in
$bashbash.sh Conclusion To sum up, this was all about the use of the nested “for” loop in the Bash script of the Ubuntu 20.04 Linux system. We have discussed the examples to see a simple “for” loop in Bash, nested “for” loop, and a one-line nested “for” loop in Bash sc...
for n in {1..7}; do echo $n done Once the shell script is executed, all the values in the range are listed, similar to what we had insimple loops. Bash For Loop with Ranges Example Additionally, we can include a value at the end of the range that is going to cause thefor loop...
