NAME

bps - List all BPF programs. 'ps' for BPF programs.

SYNOPSIS

bps [bpf-prog-id]

DESCRIPTION

bps lists all BPF programs loaded into the kernel. It is similar to the ps command but for the BPF programs.

Each loaded bpf program is identified by an unique integer (i.e. bpf-prog-id or simply BID). If a bpf-prog-id is specified, the maps used by bpf-prog-id will also be listed.

EXAMPLES

List all BPF programs loaded into the kernel:
