How to show symbols in ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, no section header

Question

Got a file which I do not know how to list its symbols, file command says:

]# file <file-name>
ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, no section header

nm and nm -D says no symbols in it. How to get the symbols?

Answer 1

How to get the symbols?

The nm -D is guaranteed to not produce any output for a statically linked binary -- dynamic symbols are never present in such binaries.

The fact that nm produces no output and that file says no section header means that this binary is fully stripped, i.e. all symbols and section info has been removed from it.

There is no way to get symbols from this binary -- you need to get the original (unstipped) one if you need symbolic info.
