How to prompt user to define a variable?

Hi everyone,

Is it possible to define blank vaianbles and prompt user to fill them during the script execution?

A very simple example:

Code:
INPUT=
OUTPUT=

cut -f1-4 $INPUT | sed 's/hello/goodbye/g' | sort -uV > $OUTPUT

Thank you in advance!

Best wishes
