3-h, --help
4 Print short help message (similar to **bpftool help**).
5
6-V, --version
7 Print bpftool's version number (similar to **bpftool version**), the
8 number of the libbpf version in use, and optional features that were
9 included when bpftool was compiled. Optional features include linking
10 against libbfd to provide the disassembler for JIT-ted programs
11 (**bpftool prog dump jited**) and usage of BPF skeletons (some
12 features like **bpftool prog profile** or showing pids associated to
13 BPF objects may rely on it).
14
15-j, --json
16 Generate JSON output. For commands that cannot produce JSON, this
17 option has no effect.
18
19-p, --pretty
20 Generate human-readable JSON output. Implies **-j**.
21
22-d, --debug
23 Print all logs available, even debug-level information. This includes
24 logs from libbpf as well as from the verifier, when attempting to
25 load programs.
26
27-l, --legacy
28 Use legacy libbpf mode which has more relaxed BPF program
29 requirements. By default, bpftool has more strict requirements
30 about section names, changes pinning logic and doesn't support
31 some of the older non-BTF map declarations.
