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  version  number  (similar  to bpftool version), 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.

          -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.
