DESCRIPTION

13     This program allows you to get information about ELF/PE/MZ and CLASS
14     files in a simple way.
15
16     All those command-line flags are also available under the i command in
17     radare2. Type i? for help.
18
19     -@ addr     Show information (symbol, section, import) of the given ad‐
20                 dress
21
22     -A          List sub-binaries and their associated arch-bits pairs
23
24     -a arch     Set arch (x86, arm, .. accepts underscore for bits x86_32)
25
26     -b bits     Set bits (32, 64, ...)

35                 Create [elf,mach0,pe] for arm and x86-32/64 tiny binaries
36                 where 'C' is an hexpair list of the code bytes and ':D' is an
37                 optional concatenation to describe the bytes for the data
38                 section.

71                 tions listing (and maybe others in the future) i.e 'rabin2 -K
72                 md5 -S /bin/ls'
