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 ...
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...
# loop through strings resulting from a command for value in $(Linux command) do commands done # loop through increment or decrement numbers # traditional procedural for loop for (( i=0; i<10; i++) do commands done According to the above syntax, the starting and ending block of for...
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...

/bin/bashusers=(John Harry Jake Scott Philis)foruin"${users[@]}"doecho"$uis a registered user"done With this syntax, you will loop over theusersarray, with each name being temporarily stored inu. The[@]syntax tells the interpreter that this is an indexed array that we'll be iterating...
## declare an array variable declare -a arr=("element1" "element2" "element3") ## now loop through the above array for i in "${arr[@]}" do echo "$i" # or do whatever with individual element of the array done # You can access them using echo "${arr[0]}", "${arr[1]}...
for n in {1..7..2}; do echo $n done Bash For Loop Incremented Values From the above example, you can see that theloopincremented the values inside the curly braces by 2 values. Bash For Loops with Arrays You can also easily iterate through values defined in an array using afor Loop...
For example, let us use the continue statement to iterate through a range of number and when it reaches a specific number, which in this case will be ‘4’, the continue statement will exit the iteration and go back to the beginning of the loop to begin the next iteration. for i in...
