A 'for loop' is a bash programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement i.e. it is the repetition of a process within a bash script. Tutorial details For example, you can run UNIX command or task 5 times or ...
For example, the following loop would only print the numbers from one to three: for ((i=1;i<=10;i++)); do echo $i if [ $i -eq 3 ]; then break fi done You can also use acontinuestatement to skip a loop iteration. The loop continues and moves to the next iteration but the...
The skip and continue loop is used when you want to skip the loop for the specific value and then continue the loop from another value. The syntax is given as: for I in 1 2 3 4 5 do if [condition] then continue #Go to next iteration of I in the loop and skip statements3 ...

The nested while loop is beneficial for multi-level iteration and complex logic handling. Let’s create a 3×3 2D array using nested while loop in Bash: #!/bin/bash i=1 while [ $i -le 3 ] do j=1 while [ $j -le 3 ]
we’ve created an array namedfruitswith three elements: ‘apple’, ‘banana’, and ‘cherry’. The ‘for’ loop then iterates over each element in the array. For each iteration, the current element’s value is stored in thefruitvariable, which we then use in theechocommand to print out...
