Ever so often I want to do two things:

1. read the table of symbols exported from a shared library/executable
2. read the soname of a library along with shared library dependencies

Here's how to do both with 3 tools: nm, readelf, objdump. For the sake of brevity I will be working on a DSO¹ called libtest.so.

Reading symbol table

nm -CD libtest.so
readelf -sD libtest.so  # no demangling!
objdump -CT libtest.so

Dynamic section

readelf -d libtest.so
objdump -p libtest.so

ldd also works on shared libraries.
