I have a requirement of masking few specific fields in the UNIX file. The details are as following-
File is fixed length file with each record of 250 charater length.
2 fields needs to be masked – the positions are 21:30 and 110:120
The character by character making needs to be done which means one character in this field (21:30 and 110:120) should be replaced with some another character.
The replacement patterns should be kept in a separate file. For example
Code:
A:B
B:C
Which means A should be replaced with B , B with C and so on.

srec_stewie - Stewie's binary file format
DESCRIPTION
If you have a URL for documentation of this format, please let me know.
Any resemblance to the Motorola S-Record is superficial, and extends only to the data records. The header records and termination records
are completely different. None of the other Motorola S-Records record type are available.
The Records
All records start with an ASCII capital S character, value 0x53, followed by a type specifier byte. All records consist of binary bytes.
The Header Record
Each file starts with a fixed four byte header record.
+-----+------+------+------+
|0x53 | 0x30 | 0x30 | 0x33 |
+-----+------+------+------+
The Data Records
Each data record consists of 5 fields. These are the type field, length field, address field, data field, and the checksum. The lines
always start with a capital S character.
+-----+------+---------------+---------+------+----------+
|0x53 | Type | Record Length | Address | Data | Checksum |
+-----+------+---------------+---------+------+----------+
Type The type field is a one byte field that specifies whether the record has a two-byte address field (0x31), a three-byte address
field (0x32) or a four-byte address field (0x33). The address is big-endian.
Record Length
The record length field is a one byte field that specifies the number of bytes in the record following this byte.
Address This is a 2-, 3- or 4-byte address that specifies where the data in the record is to be loaded into memory.
Data The data field contains the executable code, memory-loadable data or descriptive information to be transferred.
Checksum
The checksum is a one byte field that represents the least significant byte of the one's complement of the sum of the values repre-
sented by the bytes making up the record's length, address, and data fields.
The Termination Record
Each file ends with a fixed two byte termination record.
+-----+------+
|0x53 | 0x38 |
+-----+------+
Size Multiplier
In general, binary data will expand in sized by approximately 1.2 times when represented with this format.
EXAMPLE
Here is an hex-dump example file. It contains the data "Hello, World[rq] to be loaded at address 0.
0000: 53 30 30 33 53 31 10 00 00 48 65 6C 6C 6F 2C 20 S003S1...Hello,
0010: 57 6F 72 6C 64 0A 9D 53 38 World..S8
