Help me out - why do you set the field seprator to " when there is NO " in your input file? $2 (requested in post#1) will be the empty string... as will $3 requested in post#4.
I was expecting this from you only @RudiC... Actual input is very thin to paste here..this is why I specifically mentioned in 2nd response that I need to encode $2 using base64 (only).. forget the
please for now.
the other problem is that its a million lines file and every $2 has to be encoded using base64.. the [g]awk runs out or whatevery happens, it is giving me scambled results instead of line by line encoding using external command of base64 in linux/debian.
I need to install the base64 encryption method on a UNIX machine under AIX5.2.
I've received a tar file but it is only C source , can you help me please. (sending me a binary base64 or to compile my source)
Thanks by advance (3 Replies)
I am porting a awk script from Windows to unix
I_SALE_MEDIA=$67
if ((I_VOID_FLAG == "Y") && (I_SALE_MEDIA == 0))
NOW consider the case where I_SALE_MEDIA i.e $67 is "000"
The above comparison works fine in Windows , but to make it work in
Unix , I had to change the above as follows :

Hi Everyone,
I am confused with the output of the input file and I am using below command in script to get the expected output.
Also I want to add another condition using logical AND (&&) in place of $2=="L"{$4=0-$4} as $2=="L" && $3=="L" {$4=0-$4} but I am getting some awk error.
Can someone... (6 Replies)
And is there a good way of taking them out?
I've been playing around a bit with using b64 to embed images in HTML (and trying to stay within the spec). I've noticed that with openssl's base64 encoder, the output files have newline characters @ every 65th column or so. This renders them useless,... (2 Replies)
Hi everyone
I am very new at awk and to me the task I need to get done is very very challenging... Nevertheless, after admiring how fast and elegant issues are being solved here I am sure this is my best chance.

bio_f_base64
BIO_f_base64(3) OpenSSL BIO_f_base64(3)NAME
BIO_f_base64 - base64 BIO filter
SYNOPSIS
#include <openssl/bio.h>
#include <openssl/evp.h>
BIO_METHOD * BIO_f_base64(void);
DESCRIPTION
BIO_f_base64() returns the base64 BIO method. This is a filter BIO that base64 encodes any data written through it and decodes any data
read through it.
Base64 BIOs do not support BIO_gets() or BIO_puts().
BIO_flush() on a base64 BIO that is being written through is used to signal that no more data is to be encoded: this is used to flush the
final block through the BIO.
The flag BIO_FLAGS_BASE64_NO_NL can be set with BIO_set_flags() to encode the data all on one line or expect the data to be all on one
line.
NOTES
Because of the format of base64 encoding the end of the encoded block cannot always be reliably determined.
RETURN VALUES
BIO_f_base64() returns the base64 BIO method.
EXAMPLES
Base64 encode the string "Hello World
" and write the result to standard output:
BIO *bio, *b64;
char message[] = "Hello World
";
b64 = BIO_new(BIO_f_base64());
bio = BIO_new_fp(stdout, BIO_NOCLOSE);
bio = BIO_push(b64, bio);
BIO_write(bio, message, strlen(message));
BIO_flush(bio);
BIO_free_all(bio);
Read Base64 encoded data from standard input and write the decoded data to standard output:
BIO *bio, *b64, *bio_out;
char inbuf[512];
int inlen;
b64 = BIO_new(BIO_f_base64());
bio = BIO_new_fp(stdin, BIO_NOCLOSE);
bio_out = BIO_new_fp(stdout, BIO_NOCLOSE);
bio = BIO_push(b64, bio);
while((inlen = BIO_read(bio, inbuf, 512)) > 0)
BIO_write(bio_out, inbuf, inlen);
BIO_free_all(bio);
BUGS
The ambiguity of EOF in base64 encoded data can cause additional data following the base64 encoded block to be misinterpreted.
There should be some way of specifying a test that the BIO can perform to reliably determine EOF (for example a MIME boundary).
