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.
