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 version number (similar to bpftool version).

-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.

-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.

-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.
