Hi all,

i have a script.

When i run the script, on the prompt i use: $> . ./blah; i have an undefined variable error.

But when i run the script using $> ./blah ; it works fine.

I know it was something to do with FORK() process.

But i have a simple script , using while loop.

#!/bin/sh

answer=0

while [ "$answer" -gt 10 ];

do

echo "Hello"

done

It's complaining my "answer" variable.

How to fix the problem? Do i need to use PATH?

Please help
