| -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. |
