#!/usr/bin/ksh

fname="$1"

fldr="/tmp"

if [ -f "$fldr/$fname" ]
then
echo "File exists... congrats !!"
else
echo "File don't exists..!!"
fi

$1 is the first input parm
$2 is the second input parm
You can max input 9 parms $1-$9

You should run the script like this

./test_program file_name folder_name

then file_name will be assigned to $1
folder_name will be assigned to $2

I guess we can have more than 9 params using shift command....

It is long time since I used these I don't remember well.

mahendramahendr is right

for example
./test 1 2 3 4 5 6 7 8 9 10 11 12

#!/bin/sh

while [ -n "$1" ];do
   echo "$1 $2"
   shift 2
done

The output should be

1 2
3 4
5 6
7 8
9 10
11 12

Hope to help you
