Selva,

How exactly is the file coming to the server? Is it through FTP? If so, what mode are you using for transferring? ASCII or BINARY?

Note that if the FTP transfer mode is ASCII, then the files might have ^M characters or square boxes appended at the end of each line, which may result in the failure of your script. Hence, BINARY mode of FTP transfer is always preferred.

HTH,
