Print Unknown Number of User Inputs in awk
Hello,

I am new to awk and I am trying to figure out how to print an output based on user input.

For example:

Code:
ubuntu:~/scripts$ steps="step1, step2, step3"

ubuntu:~/scripts$ echo $steps
step1, step2, step3

I am playing around and I got this pattern that I want:

Code:
ubuntu:~/scripts$ echo $steps | awk -F, '{print "Step Taken:" "\n" "- "$1 "\n" "-"$2 "\n" "-" $3}'

Step Taken:
- step1
- step2
- step3

The question is this:

What if the users input 4 or more steps (always separated by comma which I will use as a field separator just like the example above)?

How can I print an output that will include step4 or more like this?

Code:
Step Taken:
- step1
- step2
- step3
- step4
- step5

So on and so forth...

Thanks!
