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.
