Validating inputs from a file
Hi,
I have a file called inputs. Now that file has the values like this: 1 2 3 Now In my script called 'get.sh' I do this : exec < inputs read a b c d Now I know that there will not be any value in d. How can I check it. I need the exact condition for checking whether the variable has any value or not. Thanks in advance |
