Rabin is able to get all the imported objects, as well as their offset at the PLT, this information is quite useful, for example, to recognize wich function is called by a call instruction.
$ rabin -i /bin/ls | head

The flag -v will output human readable output.
$ rabin -iv /bin/ls

Combined with -vv, we get two new columns, bind (LOCAL, GLOBAL, etc.) and type (OBJECT, FUNC, SECTION, FILE, etc.)
$ rabin -ivv /bin/ls
[Imports]
Memory address File offset Bind Type Name
0x08049484 0x00001484 GLOBAL FUNC abort
0x08049494 0x00001494 GLOBAL FUNC __errno_location
0x080494a4 0x000014a4 GLOBAL FUNC sigemptyset
0x080494b4 0x000014b4 GLOBAL FUNC sprintf

Again, with -r we can automatically flag them in radare.
