Hi krk...

From your limited octal dump I still cannot discern any patterns that work according to your original post...

I therefore have to bow out gracefully as I cannot help you any further...

when i execute the command
Code:
file <binary_filename>

i get below message.

0420 Alliant virtual executable common library not stripped.

does that ring any bells ?

Not really.

What makes you suspect there's anything useful in this file to extract?

I need to decode the binary file ,convert it in ASCII and load its contents into oracle table.

when i do a
Code:
file -i <filename>

i get below o/p
Code:
application/octet-stream

As per my source , this a binary file encoded with base32.
Coud you please let me how should i decode the file.I mean what shoudl be my first step. I have the specification of file like

Code:
No	Field Name	        Type	        Offset  ASCII_Length	Bytes	    Binary Type
C1	Record Type	Number(3)	 1	  3	                       1    Unsigned Char
C2	Call Date	        Date	         4	  8                            4    Long
C3	Operator	        Number (4)	 12	  4	                       2    Unsigned short
C4	Segment Number	Number(3)	 16	  3	                       1    Unsigned Char

help appreciated.

As per RFC 3548,
Quote:
The Base16, Base32, and Base64 Data Encodings July 2003 A 33-character subset of US-ASCII is used, enabling 5 bits to be represented per printable character. (The extra 33rd character, "=", is used to signify a special processing function.)
So none of the samples you presented by now can by any means be base32 coded.

Is it possible you have a fixed length record file to be interpreted according to above scheme?
