File type identification is done using -I. With this option, rabin2 prints information on a binary type, like its encoding, endianness, class, operating system:

$ rabin2 -I /bin/ls
arch     x86
binsz    128456
bintype  elf
bits     64
canary   true
class    ELF64
crypto   false
endian   little
havecode true
intrp    /lib64/ld-linux-x86-64.so.2
lang     c
linenum  false
lsyms    false
machine  AMD x86-64 architecture
maxopsz  16
minopsz  1
nx       true
os       linux
pcalign  0
pic      true
relocs   false
relro    partial
rpath    NONE
static   false
stripped true
subsys   linux
va       true

To make rabin2 output information in format that the main program, radare2, can understand, pass -Ir option to it:

$ rabin2 -Ir /bin/ls
e cfg.bigendian=false
e asm.bits=64
e asm.dwarf=true
e bin.lang=c
e file.type=elf
e asm.os=linux
e asm.arch=x86
e asm.pcalign=0
