c++filt is a GNU Binutils command that turns the mangled names the C++ compiler gives to symbols back into the original, human-readable function signatures. Piping in names starting with _ZN from linker error messages or nm and objdump output shows them with their namespaces and argument types. The -C option of nm and objdump has the same functionality built in.
