Infinite User Input Variables In Bash? [duplicate]

Question

Currently, I'm working on a Bash script that would allow for an infinite amount of input from the user.

Currently, I have the script running only with a specific number of variables.

I'm using the following line:

read var1 var2 var3

My goal is to have it so that the user can input as many variables into the script without having to add a bunch of variables

i think what you want is a variable number of inputs. see this answer for more info stackoverflow.com/questions/10307280/… — aensm

Use an array: read -a vars. Ask for help if you need assistance with arrays. — glenn jackman
