- -h, --help
- Print short help message (similar to **bpftool help**).
- -V, --version
- Print bpftool's version number (similar to **bpftool version**), the
- number of the libbpf version in use, and optional features that were
- included when bpftool was compiled. Optional features include linking
- against libbfd to provide the disassembler for JIT-ted programs
- (**bpftool prog dump jited**) and usage of BPF skeletons (some
- features like **bpftool prog profile** or showing pids associated to
- BPF objects may rely on it).
- -j, --json
- Generate JSON output. For commands that cannot produce JSON, this
- option has no effect.
- -p, --pretty
- Generate human-readable JSON output. Implies **-j**.
- -d, --debug
- Print all logs available, even debug-level information. This includes
- logs from libbpf as well as from the verifier, when attempting to
- load programs.
- -l, --legacy
- Use legacy libbpf mode which has more relaxed BPF program
- requirements. By default, bpftool has more strict requirements
- about section names, changes pinning logic and doesn't support
- some of the older non-BTF map declarations.
- See https://github.com/libbpf/libbpf/wiki/Libbpf:-the-road-to-v1.0
- for details.
