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.
