       ITER-COMMANDS := { pin | help }

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 op‐
	      tional 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 skele‐
	      tons (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.
