Hi,

When I run the following command, sh channels.ksh test2.txt, I get the "Cannot Open" error. The file test2.txt is the input file for the script and it does exist in the same folder as the shell script. Can somebody help me in finding what I am missing here?

You are missing the path where is file located.

The file is in the same directory as that of the script.
I get the same error even if I give the path for the file.

Can it be that your $PATH do not include the folder .
Try to start your script with a point and slash at the beginning like following.
sh ./channels.ksh test2.txt.

The second tip I have : check the permissions from the file test2.txt.

Use chmod 777 test.txt and you will sure the permissions are OK

It´s only a try.
