I need to convert a binary file which in encoded using base32 encoding technique and convert that into readible ASCII so that i can load the same in DB.
is there any command to do the same.
sample from the binary file lools like :
ascii file looks like (tab seperated fixed length):
help much appreciated.
I tried using python base64 , but in vain .

Hello,
How to i determine via ftp commandline if files on ftp server is ascii or binary files. Like every other comon windows ftp program does it automatically.

I tried to decode a binary script using the command 'uudecode'. but it is giving error as 'No begining line'.
'uudecode -o <outfile name> <binary file>'

hi
i am receiving a file from one system , i have to verify the format of the file data i.e whether the data is in acii format or binary format,
please help
thanks in advance

Hi,
Is there a way to convert the binary file to ascii . the binary file is pipe delimited.
from source the file(pipe delimited) is ftped to mainframe and from mainframe it is ftped to the unix box using binary format. Is there a way to change it back to ascii and view it?
Thanks! (3 Replies)
Hello all,
I am working with ftp servers in unix, and always I have to get and put files but I don't know exactly if I have to get or put them as an ascii or binary. Some files that I use are: .txt, .sav, .fmb, .pct, .sh, .ksh, .dat, .log.
Somebody can tell me what is the difference between... (2 Replies)
what is the diff between ascii and binary file.
my understand is that..
ascii file - has only line feed - \n in it
where as
binary file - has both line feed and carriage return in it- \r\n
is that correct.
also,what is the ksh command to identify whether it is a binary or ascii... (1 Reply)
Hi All,
I have a binary file which is being exported from a Database, and i need to convert that to ASCII format. How can i achieve that? And this solution should work for any file which is given to us; means they will give different files from different tables.
Thanks in advance. (8 Replies)
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...

addr2ascii
ADDR2ASCII(3) BSD Library Functions Manual ADDR2ASCII(3)NAME
addr2ascii, ascii2addr -- Generic address formatting routines
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <arpa/inet.h>
char *
addr2ascii(int af, const void *addrp, int len, char *buf);
int
ascii2addr(int af, const char *ascii, void *result);
DESCRIPTION
The routines addr2ascii() and ascii2addr() are used to convert network addresses between binary form and a printable form appropriate to the
address family. Both functions take an af argument, specifying the address family to be used in the conversion process. (Currently, only
the AF_INET and AF_LINK address families are supported.)
The addr2ascii() function is used to convert binary, network-format addresses into printable form. In addition to af, there are three other
arguments. The addrp argument is a pointer to the network address to be converted. The len argument is the length of the address. The buf
argument is an optional pointer to a caller-allocated buffer to hold the result; if a null pointer is passed, addr2ascii() uses a statically-
allocated buffer.
The ascii2addr() function performs the inverse operation to addr2ascii(). In addition to af, it takes two arguments, ascii and result. The
ascii argument is a pointer to the string which is to be converted into binary. The result argument is a pointer to an appropriate network
address structure for the specified family.
The following gives the appropriate structure to use for binary addresses in the specified family:
AF_INET struct in_addr (in <arpa/inet.h>)
AF_LINK struct sockaddr_dl (in <net/if_dl.h>)
AF_INET and AF_LINK constants are defined in <sys/socket.h>
RETURN VALUES
The addr2ascii() function returns the address of the buffer it was passed, or a static buffer if the a null pointer was passed; on failure,
it returns a null pointer. The ascii2addr() function returns the length of the binary address in bytes, or -1 on failure.
EXAMPLES
The inet(3) functions inet_ntoa() and inet_aton() could be implemented thusly:
#include <sys/socket.h>
#include <arpa/inet.h>
char *
inet_ntoa(struct in_addr addr)
{
return addr2ascii(AF_INET, &addr, sizeof addr, 0);
}
int
inet_aton(const char *ascii, struct in_addr *addr)
{
return (ascii2addr(AF_INET, ascii, addr)
== sizeof(*addr));
}
In actuality, this cannot be done because addr2ascii() and ascii2addr() are implemented in terms of the inet(3) functions, rather than the
other way around.
ERRORS
When a failure is returned, errno is set to one of the following values:
[ENAMETOOLONG] The addr2ascii() routine was passed a len argument which was inappropriate for the address family given by af.
[EPROTONOSUPPORT] Either routine was passed an af argument other than AF_INET or AF_LINK.
[EINVAL] The string passed to ascii2addr() was improperly formatted for address family af.
SEE ALSO inet(3), linkaddr(3), inet(4)HISTORY
An interface close to this one was originally suggested by Craig Partridge. This particular interface originally appeared in the INRIA IPv6
implementation.
AUTHORS
Code and documentation by Garrett A. Wollman, MIT Laboratory for Computer Science.
BUGS
The original implementations supported IPv6. This support should eventually be resurrected. The NRL implementation also included support
for the AF_ISO and AF_NS address families.
The genericity of this interface is somewhat questionable. A truly generic interface would provide a means for determining the length of the
buffer to be used so that it could be dynamically allocated, and would always require a ``struct sockaddr'' to hold the binary address.
Unfortunately, this is incompatible with existing practice. This limitation means that a routine for printing network addresses from arbi-
trary address families must still have internal knowledge of the maximum buffer length needed and the appropriate part of the address to use
as the binary address.
