.Sh DESCRIPTION
This program allows you to get information about ELF/PE/MZ and CLASS files in a simple way.
.Pp
All those command-line flags are also available under the i command in radare2. Type i? for help.
.Bl -tag -width Fl
.It Fl @ Ar addr
Show information (symbol, section, import) of the given address
.It Fl A
List sub-binaries and their associated arch-bits pairs
.It Fl a Ar arch
Set arch (x86, arm, .. accepts underscore for bits x86_32)
.It Fl b Ar bits
Set bits (32, 64, ...)
.It Fl B Ar addr
Override baddr
.It Fl c
List classes
.It Fl cc
List classes in header format
.It Fl C Ar [fmt:C[:D]]
Create [elf,mach0,pe] for arm and x86-32/64 tiny binaries where 'C' is an hexpair list of the code bytes and ':D' is an optional concatenation to describe the bytes for the data section.
.It Fl d
Show debug/dwarf information
.It Fl D Ar lang symbolname|-
Demangle symbol name (or - to read from stdin) for lang (cxx, swift, java, cxx, ..)
.It Fl e
Show entrypoints for disk and on-memory
.It Fl ee
Show constructor/destructors (extended entrypoints)
.It Fl f Ar subbin
Select sub-binary architecture. Useful for fat-mach0 binaries
.It Fl F Ar binfmt
Force to use that bin plugin (ignore header check)
.It Fl g
Show all possible information
.It Fl G Ar addr
Load address . offset to header
.It Fl h
Show usage help message.
.It Fl H
Show header fields (see ih command in r2)
.It Fl I
Show binary info (iI in r2)
.It Fl i
Show imports (symbols imported from libraries) (ii)
.It Fl j
Output in json
.It Fl k Ar query
Perform SDB query on loaded file
.It Fl K Ar algo
Select a rahash2 checksum algorithm to be performed on sections listing (and maybe others in the future) i.e 'rabin2 -K md5 -S /bin/ls'
.It Fl l
List linked libraries to the binary
.It Fl L
List supported bin plugins
.It Fl M
Show address of 'main' symbol
.It Fl m Ar addr
Show source line reference from a given address
.It Fl N Ar minlen:maxlen
Force minimum and maximum number of chars per string (see -z and -zz). if (strlen>minlen && (!maxlen || strlen<=maxlen))
.It Fl n Ar str
Show information (symbol, section, import) at string offset
.It Fl o Ar str
Output file/folder for write operations (out by default)
.It Fl O Ar binop
Perform binary operation on target binary (dump, resize, change sections, ...) see '-O help' for more information
.It Fl p
Disable VA. Show always physical addresses (not the same as -B0)
.It Fl P
Show debug/pdb information
.It Fl PP
Download pdb file for binary
.It Fl q
Be quiet, just show fewer data
.It Fl qq
Show less info (no offset/size for -z for ex.)
.It Fl Q
Show load address used by dlopen (non-aslr libs)
.It Fl r
Show output in radare format
.It Fl R
Show relocations
.It Fl s
Show exported symbols
.It Fl S
Show sections
.It Fl SS
Show segments
.It Fl t
Show file hashes
.It Fl T
Show Certificates
.It Fl u
Unfiltered (no rename duplicated symbols/sections)
.It Fl U
Show Resources
.It Fl v
Show version information
.It Fl V
Show binary version information
.It Fl w
Show try/catch blocks
.It Fl x
Extract all sub binaries from a fat binary (f.ex: fatmach0)
.It Fl X Ar format file ...
Package a fat or zip containing all the files passed (fat, zip)
.It Fl z
Show strings inside .data section (like gnu strings does)
.It Fl Z
Guess size of binary program
.It Fl zz
Shows strings from raw bins
.It Fl zzz
Dump raw strings to stdout (for huge files)
