Example 03: Nested For Loop in One line The nested “for” loop can also be used within the Bash code in a single line. So, we have updated the same Bash file after opening it within the nano editor as below. For the first “for” loop, we have used the values x, y, and z. ...
you can do that. So, we have decided to create one example for such a type of one-line while loop. Thus, I started the Bash file within the nano editor and added the Bash support at the first line. After that, we have initialized an integer value “i” with 2. At the following ...
