binder
A simple tool that can be used to compare binary files.
The following operators are supported:
| Operator | Description |
|---|---|
| xor (^) | Returns a list of all bytes that differ between two files. |
| and (.) | Takes two diff lists and finds the intersect. |
| or (+) | Takes two diff lists and finds the union. |
| subtract (-) | Takes two diff lists and finds the set difference. |
For example, the following command can be used to find the bytes that differ between three different binary files:
$ ./bin/binder { examples/0.txt ^ examples/1.txt } + { examples/1.txt ^ examples/2.txt }
examples/0.txt examples/1.txt examples/2.txt
00000004 65 65 45
0000000d 6e 4e 6e
0000000e 6f 4f 6f
0000000f 70 50 50
00000011 72 72 52
00000018 79 79 7a
00000019 7a 7a 79
This command can be used to find only the bytes that differ both between the first and second, and the second and third:
$ ./bin/binder { examples/0.txt ^ examples/1.txt } . { examples/1.txt ^ examples/2.txt }
examples/0.txt examples/1.txt examples/2.txt
0000000d 6e 4e 6e
0000000e 6f 4f 6f
Operator precedance is currently not supported and brackets around compound expressions are required.
