Select records based on search criteria on first column

Hi All,

I need to select only those records having a non zero record in the first column of a comma delimited file.

Suppose my input file is having data like:

"0","01/08/2005 07:11:15",1,1,"Created",,"01/08/2005"
"0","01/08/2005 07:12:40",1,1,"Created",,"01/08/2005"
"552130000","01/08/2005 07:16:53",2,3,"FIDS_Accept",,"01/08/2005"

Then I need the output having only

"552130000","01/08/2005 07:16:53",2,3,"FIDS_Accept",,"01/08/2005"

The Unix philosophy is a computer operating system idea that means the operating system provides a set of basic tools that perform a limited, well-defined function, a unified filesystem as the main method of communication, and a shell scripting and command language to combine modular tools to perform more complex workflows.
