+ITER COMMANDS
+===================

+|	**bpftool** **iter help**
+|
+|	*OBJ* := /a/file/of/bpf_iter_target.o
+
+
+DESCRIPTION
+===========
+	**bpftool iter pin** *OBJ* *PATH*
+		  A bpf iterator combines a kernel iterating of
+		  particular kernel data (e.g., tasks, bpf_maps, etc.)
+		  and a bpf program called for each kernel data object
+		  (e.g., one task, one bpf_map, etc.). User space can
+		  *read* kernel iterator output through *read()* syscall.
+
+		  The *pin* command creates a bpf iterator from *OBJ*,
+		  and pin it to *PATH*. The *PATH* should be located
+		  in *bpffs* mount. It must not contain a dot
+		  character ('.'), which is reserved for future extensions
+		  of *bpffs*.
+
+		  User can then *cat PATH* to see the bpf iterator output.
+
+	**bpftool iter help**
+		  Print short help message.
+
+OPTIONS
+=======
+	-h, --help
+		  Print short generic help message (similar to **bpftool help**).
+
+	-V, --version
+		  Print version number (similar to **bpftool version**).
+
+	-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.
+
+EXAMPLES
+========
+**# bpftool iter pin bpf_iter_netlink.o /sys/fs/bpf/my_netlink**
+
+::
+
+   Create a file-based bpf iterator from bpf_iter_netlink.o and pin it
+   to /sys/fs/bpf/my_netlink
