Hi All ,
I have a mainframe file which contains the data in EBCDIC format.I have downloaded this file from mainframe to windows in binary format(unreadable raw data).Now I want convert this file to ASCII format(readable format data) through Unix command.I have tried iconv but that is not working .Can anyone suggest me how can I convert a file from binary unreadable format to readable ascii format through unix command.

I assume you are in a Windows flavour...
I also assume you have CygWin installed...

If so look at man dd ...
