hexcmp

A simple utility intended to be used in pipeline with unix cmp -l command. Converts all three columns of cmp -l output (offset, byte value from left file, byte value from right file) to hexadecimal numbers.

Motivation

Original cmp -l output is formatted as "decimal octal octal", which is very inconvinient. Cmp does not support any commandline switches to change this output format.

hexcmp covers for this drawback.

Usage

cmp -l file1 file2 | hexcmp

Sample output

0045fd e8 eb
0045fe 37 3a
0045ff cf 90
004600 01 32
004601 00 c0

Pretty print

hexcmp supports one commandline switch: -p. It allows to print a slightly "nicer looking" output:

0045fd: e8 -> eb
0045fe: 37 -> 3a
0045ff: cf -> 90
004600: 01 -> 32
004601: 00 -> c0
