I want to send multiple values from console so that individual values are assigned to array indexes in array. Later I can use foreach loop to get those values. Thank you.
example:
Enter values from 1 to 4:
1
2
3
4
arr[0] = 1,
arr[1] = 2,
arr[2] = 3,
arr[3] = 4
If I give you directly the whole answer, you will not learn anything. Therefore I will give you the building blocks necessary to build the solution and guide you through the building steps.
1) Append to array in bash:
ARRAY=()
ARRAY+=('A')
ARRAY+=('B')
Have a look at: Bash array append
2) read syntax:
read [options] NAME1 NAME2 ... NAMEN
Have a look at: read command
3) Bash loop construct:
while read elem
do
#If end of inputs (special value for example)
#break in order to quit the loop
#do something (append to array)
done
Have a look at: Bash loops
4) Bash branching (if/else/elif/...) construct
Have a look at: Bash if/else
5) Last step, you need to put everything together:
Create an empty array, loop on the user input, check the input value via a if and break the loop if it reach a specific condition, otherwise add it to the array
Let me know if you are stuck somewhere, I will help you.
