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.
