ere is an easier version of what i want to do


#!/bin/bash
echo "Enter file name"
echo "You can enter maximum 3 file"

for (( i=1; i<=3;i++))
until [ "$*" = "" ]
do
echo "Enter file ${i}"
read fil_$i

# check whether read actuylly read something and break if it didn't
[ -z $fil_$i ] && break
# untested...

done
//do the rest of the code

the probleam is, my input needs three input. but what i want to do is
to put an optin of optional break, say instead of three, i have only
one input ...so, if i put "0", the code should ixit for loop and do
the rest of the things.
how can i do that?
