+DESCRIPTION
+===========
+	**bpftool perf { show | list }**
+		  List all raw_tracepoint, tracepoint, kprobe attachment in the system.
+
+		  Output will start with process id and file descriptor in that process,
+		  followed by bpf program id, attachment information, and attachment point.
+		  The attachment point for raw_tracepoint/tracepoint is the trace probe name.
+		  The attachment point for k[ret]probe is either symbol name and offset,
+		  or a kernel virtual address.
+		  The attachment point for u[ret]probe is the file name and the file offset.
+
+	**bpftool perf help**
+		  Print short help message.
