Examining binary files in Linux

A few different tips assembled together for one to find out information about an executable binary in Linux.

To assert that the file is a binary executable (or some other file types):

file file.bin

To see what the legible strings within the binary file is:

strings file.bin

To do a hexdump of the file:

od -tx1 file.bin

To disassemble a compiled binary:

readelf -b file.bin -m i8086

To disassemble an binary object file:

objdump -DaflSx -b file.bin -m i8086

To list the symbols in an object file:

nm file.bin

To see what shared library it's being linked with:

ldd file.bin

To see a trace of what libraries it calls / files open dynamically:

dtrace file.bin

To debug through it's execution:

gdb file.bin

To unmangle function names if code is compiled with C++:

echo "<mangled_symbol_name>" | c++filt
