Now comes the fun part; we need to set up the for loop, which using the iterator “i” will iterate through the array’s contents and perform the display function. You can do it as such: This line sets up the loop. With the “$” symbol, we are specifying that we are trying to ...
The way command substitution works is, the command gets first executed and then the for loop will iterate through the entire output of the command. The command to be iterated upon is placed inside “$()“. In the above snippet: In the linefor file in $(ls); do, the$(ls)part execute...
A‘for’ loop is a control flow statement that allows code to be executed repeatedly. When it comes to arrays, a ‘for’ loop can iterate through each element, allowing you to perform operations on individual items. Here’s an example of using a ‘for’ loop to loop through an array in...
Use for loop with array for every element In this method, you can use a variable that will be used to print every element of the array. You can use any name for the variable to store the value of the element for the ongoing iteration. Here, I went with theitemas a variable. And t...
