to specify the iterator variable “I” after the word “for”. To mention, the range of iterations in brackets must be followed by the word “in” as per the below image. The range has been defined from 1 to 10 with two dots in between. The “for” loop will continue to run until...
The script first prompts the user to input a number and checks if the input is a valid number. Then, it uses a for loop to iterate from 1 to 10 and prints the multiplication table of the input number for each iteration. 4. Write a Bash script that uses a while loop to continuously ...
In Bash, for loop is commonly used to transverse the elements of a list, array, string, range, etc. We can also use it to iterate/repeat the execution till the specified condition. The main purpose of the loop is basically to execute tasks repeatedly. So, we can use it to repeat any...
You can use the sequence expression tospecify a rangeof numbers or characters by defining the start and the end point of the range. The sequence expression takes the following form: {START..END} Copy Here is an example loop that iterates through all numbers from 0 to 3: fori in{0..3...
This type of for loop is characterized by counting. The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times wit...
