Unix Format Issue
I am creating ASCII file from Oracle procedure into Unix box.
Quote:
The ASCII file would have a complete string with more that 50K bytes.
I want this ASCII file should has 80 bytes per line,with NO CRLF.
I undertstand there is NO CRLF as I am writing it into one complete string .. but need to know what is best way to format the file with 80bytes per line only before handing over to another program.
Thanks in advance
regards
anan

Does anybody know or guide me on how to remove the first N bytes and the last N bytes from a binary file? Is there any AWK or SED or any command that I can use to achieve this?
Your help is greatly appreciated!!

Hi,
If I want to copy a 1024 byte data stream in to the target location in 3-bytes chunk, I guess I can use the following script.
dd bs=1024 count=3 if=/src of=/dest
But, I would like to know, how to do it via a C program. I have tried this with memcpy(), that did not help. (3 Replies)

srec_ti_tagged
srec_ti_tagged(5) File Formats Manual srec_ti_tagged(5)
NAME
srec_ti_tagged - Texas Instruments Tagged (SDSMAC) file format
DESCRIPTION
This format is also known as the TI-Tagged or TI-SDSMAC format.
This format allows binary files to be uploaded and downloaded between two computer systems, typically between a computer system (such as a
PC, Macintosh, or workstation) and an emulator or evaluation board for microcontrollers and microprocessors.
The Lines
Unlike many other object formats, the lines themselves are not especially significant. The format consits of a number of tagged fields,
and lines are composed of a series of these fields.
Tag Description
-------------------------------------
* Data byte.
: End of file.
0 File header (optional).
7 Checksum.
8 Dummy checksum (ignored).
9 Address.
B Data word.
F End of data record.
K Program identifier (optional).
Data Byte
+--+---+---+
|B | n | n |
One byte of data. The nn is 8-bit big-endian hexadecimal. +--+---+---+
End of File
+--+------+
|: | CRLF |
The end of data is indicated by this tag. The end of line sequence+(LF-on+Unix systems, CRLF on PCs) follows this tag.
File Header
+--+--------+----------+
|0 | length | filename |
The optional start-of-file record begins with a tag character-('0')-and-a-12-character file header. The first four characters are the byte
count of the file data. The remaining 8 characters are the name of the file and may be any ASCII characters, blank padded.
Checksum
+--+---+---+---+---+
|7 | n | n | n | n |
The checksum is the 2s complement sum of the 8-bit ASCII values+of-characters,-beginning with the first tag character and ending with the
checksum tag character (7). The nnnn is 16-bit big-endian hexadecimal.
Dummy Checksum
+--+---+---+---+---+
|8 | n | n | n | n |
The checksum is the 2s complement sum of the 8-bit ASCII values-of-characters, beginning with the first tag character and ending with the
checksum tag character (8). The nnnn is 16-bit big-endian hexadecimal.
Address
+--+---+---+---+---+
|9 | n | n | n | n |
Addresses may be given for any data byte, but none is mandatory.--The-file-begins at 0000 if no address is given before the first data
field. The nnnn is 16-bit big-endian hexadecimal.
Data Word
+--+---+---+---+---+
|B | a | a | b | b |
Two bytes of data. The aa and bb are each 8-bit big-endian hexadecimal.---+---+
End of Record
+--+------+
|F | CRLF |
The end of line sequence (LF on Unix systems, CRLF on PCs) is escaped-using this tag. The checksum is reset to zero at this point.
Program Identifier
+--+---+---+---+---+------+
|K | n | n | n | n | text |
The program identifier can contain a brief description-of+the+program,-or-can be empty (i.e. the text portion is optional). The nnnn
length (hex) of the field includes the `K', the length and the text; it is at least 5.
Size Multiplier
In general, binary data will expand in sized by approximately 2.9 times when represented with this format.
EXAMPLE
Here is an example TI-Tagged file. It contains the data "Hello, World[rq] to be loaded at address 0x0100.
