37DESCRIPTION
38===========
39 *bpftool* allows for inspection and simple modification of BPF objects
40 on the system.
41
42 Note that format of the output of all tools is not guaranteed to be
43 stable and should not be depended upon.
44
45OPTIONS
46=======
47 -h, --help
48 Print short help message (similar to **bpftool help**).
49
50 -v, --version
51 Print version number (similar to **bpftool version**).
52
53 -j, --json
54 Generate JSON output. For commands that cannot produce JSON, this
55 option has no effect.
56
57 -p, --pretty
58 Generate human-readable JSON output. Implies **-j**.
59
60 -m, --mapcompat
61 Allow loading maps with unknown map definitions.
62
63 -n, --nomount
64 Do not automatically attempt to mount any virtual file system
65 (such as tracefs or BPF virtual file system) when necessary.
