DESCRIPTION

36          bpftool allows for inspection and simple modification of BPF objects
37          on the system.
38
39          Note that format of the output of all tools is not guaranteed to  be
40          stable and should not be depended upon.
41

OPTIONS

43          -h, --help
44                 Print short help message (similar to bpftool help).
45
46          -V, --version
47                 Print version number (similar to bpftool version).
48
49          -j, --json
50                 Generate  JSON output. For commands that cannot produce JSON,
51                 this option has no effect.
52
53          -p, --pretty
54                 Generate human-readable JSON output. Implies -j.
55
56          -m, --mapcompat
57                 Allow loading maps with unknown map definitions.
58
59          -n, --nomount
60                 Do not automatically attempt to mount any virtual file system
61                 (such as tracefs or BPF virtual file system) when necessary.
62
63          -d, --debug
64                 Print  all logs available, even debug-level information. This
65                 includes logs from libbpf as well as from the verifier,  when
66                 attempting to load programs.
