You can inspect and modify object files (including executables) using the GNU Binary Utilities (binutils), a set of tools that also includes the GNU assembler (as) and linker (ld).
Example 6.2. Using objdump
objdump -d lab0 > lab0_dump.txt will disassemble the executable file lab0 and send the results to the file lab0_dump.txt, creating or overwriting the file as necessary.
References to further reading on binutils can be found in Section A.5.5, “More on the GNU Binary Utilities (binutils)”.
Table 6.4. Selected commands from GNU Binary Utilities (binutils)
| Command | Action |
|---|---|
| Display the symbol table of the given object file |
| Disassemble the given object file, sending the results to stdout |
| List all strings found in the given object file |
