So I have a file containing one long line of hex (converted from BER ASN.1), i.e.
I want to find all occurrences between the hex pairs 84 and a7 and replace these values by (length)(value) where length = 02 if value > 127dec, otherwise 01. And value should be incremented (beginning at 0) for each occurrence.
value will be equal to 2 bytes (4 places) where length = 02.
HI
Hi I have a character string which contains some special characters and I need it to display as a hex string.
For example, the sample i/p string: ×¥ïA Å gïÛý and
the o/p should be : D7A5EF4100C5010067EFDBFD
Any pointers or sample code pls. (5 Replies)
I have a lot of very large hex files that I need to change one value at the same offset and save to another file. I have a script that finds each file and just need to put an operator for each file.
I think sed might be able to do this but I have not used it before and would like some help. If... (8 Replies)

srec_tektronix - Tektronix hexadecimal file format
DESCRIPTION
The Tektronix hexadecimal file format is no longer very common. It serves a similar purpose to the Motorola and Intel formats, usually
used to transfer data into EPROM programmers.
The Lines
Most Tektronix hex files contain only Tektronix hex lines (see the next section), which always start with a slash ("/[rq]) character.
There are only two types of lines - data lines and a termination line.
Data Lines
Data lines have five fields: address, length, checksum 1, data and checksum 2. The lines always start with a slash ("/[rq]) character.
+--+---------+--------+-----------+------+-----------+
|/ | Address | Length | Checksum1 | Data | Checksum2 |
+--+---------+--------+-----------+------+-----------+
Address This is a 4 character (2 byte) address that specifies where the data in the record is to be loaded into memory.
Data Length
The data length field is a 2 character (1 byte) field that specifies the number of character pairs (bytes) in the data field. This
field never has a value of zero.
Checksum 1
The checksum 1 field is a 2 character (1 byte) field. Its value is the 8-bit sum of the six 4-bit values which make up the address
and length fields.
Data The data field contains character pairs (bytes); the number of character pairs (bytes) is indicated by the length field.
Checksum 2
The checksum 2 field is a 2 character (1 byte) field. Its value is the least significant byte of the sum of the all the 4-bit val-
ues of the data field.
Termination Line
Termination lines have three fields: address, zero and checksum. The lines always start with a slash ("/[rq]) character.
+--+---------+------+----------+
|/ | Address | Zero | Checksum |
+--+---------+------+----------+
Address This is a 4 character (2 byte) address that specifies where to begin execution.
Zero The data length field is a 2 character (1 byte) field of value zero.
Checksum
The checksum 1 field is a 2 character (1 byte) field. Its value is the 8-bit sum of the six 4-bit values which make up the address
and zero fields.
Size Multiplier
In general, binary data will expand in sized by approximately 2.4 times when represented with this format.
EXAMPLE
Here is an example Tektronix hex file. It contains the data "Hello, World[rq] to be loaded at address 0.
