.Sh NAME
.Nm RADIFF2
.Nd unified binary diffing utility
.Sh SYNOPSIS
.Nm radiff2
.Op Fl abcCOdrspvh
.Op Fl t Ar 0-100
.Op Fl g Ar sym
.Ar file1
.Ar file2
.Sh DESCRIPTION
radiff2 implements many binary diffing algorithms for data and code.
.Pp
.Bl -tag -width Fl
.It Fl a
Specify architecture (x86, arm, ..)
.It Fl b
Select register size bits for given arch
.It Fl c
Count number of differences.
.It Fl C
Code diffing using graphdiff algorithm. Output columns are: file-a-address, percentatge of most similar function in B file | file-b-address.
.It Fl d
Use delta diffing (slower).
.It Fl g Ar sym | off1,off2
Graph diff output of given symbol, or between two functions, at given offsets: one for each binary.
.It Fl h
Show usage help message.
.It Fl n
Suppress address names (show only addresses) when code diffing.
.It Fl O
Do code diffing with all bytes instead of just the fixed opcode bytes
.It Fl p
Use physical addressing (io.va=0)
.It Fl r
Output in radare commands as a binary patch.
.It Fl s
Calculate text distance from two files.
.It Fl t Ar 0\-100
Choose matching threshold for binary code diffing
.It Fl v
Show version information.
