57 **bpftool map { show | list }** [*MAP*]
58 Show information about loaded maps. If *MAP* is specified
61 *MAP* may match several maps which will all be shown.
63 Output will start with map ID followed by map type and

87 **bpftool map dump** *MAP*
88 Dump all entries in a given *MAP*. In case of **name**,
89 *MAP* may match several maps which will all be dumped.
91 **bpftool map update** *MAP* [**key** *DATA*] [**value** *VALUE*] [*UPDATE_FLAGS*]
92 Update map entry for a given *KEY*.
104 **bpftool map lookup** *MAP* [**key** *DATA*]
105 Lookup **key** in the map.
107 **bpftool map getnext** *MAP* [**key** *DATA*]
110 **bpftool map delete** *MAP* **key** *DATA*
111 Remove entry from the map.

120 **bpftool** **map event_pipe** *MAP* [**cpu** *N* **index** *M*]
121 Read events from a **BPF_MAP_TYPE_PERF_EVENT_ARRAY** map.

152 Freeze the map as read-only from user space. Entries from a
153 frozen map can not longer be updated or deleted with the

157 programs to the map remain unchanged.

219 Note that map update can also be used in order to change the program references
220 hold by a program array map. This can be used, for example, to change the
223 defining a prog array map, and with a main function that contains a tail call
225 processing. Note that the prog array map MUST be pinned into the BPF virtual
226 file system for the map update to work successfully, as kernel flushes prog
