DESCRIPTION
       bpftool allows for inspection and simple modification of BPF objects on
       the system.

       Note that format of the output of all tools is not guaranteed to be
       stable and should not be depended upon.

OPTIONS

       -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 LLVM or 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.

       -m, --mapcompat
              Allow loading maps with unknown map definitions.

       -n, --nomount
              Do not automatically attempt to mount any virtual file system
              (such as tracefs or BPF virtual file system) when necessary.
