1================ 2BPFTOOL 3================ 4------------------------------------------------------------------------------- 5tool for inspection and simple manipulation of eBPF programs and maps 6------------------------------------------------------------------------------- 7 8:Manual section: 8 9 10SYNOPSIS 11======== 12 13 **bpftool** [*OPTIONS*] *OBJECT* { *COMMAND* | **help** } 14 15 **bpftool** **batch file** *FILE* 16 17 **bpftool** **version** 18 19 *OBJECT* := { **map** | **program** | **cgroup** | **perf** | **net** | **feature** } 20 21 *OPTIONS* := { { **-V** | **--version** } | { **-h** | **--help** } 22 | { **-j** | **--json** } [{ **-p** | **--pretty** }] } 23 24 *MAP-COMMANDS* := 25 { **show** | **list** | **create** | **dump** | **update** | **lookup** | **getnext** 26 | **delete** | **pin** | **event_pipe** | **help** } 27 28 *PROG-COMMANDS* := { **show** | **list** | **dump jited** | **dump xlated** | **pin** 29 | **load** | **attach** | **detach** | **help** } 30 31 *CGROUP-COMMANDS* := { **show** | **list** | **attach** | **detach** | **help** } 32 33 *PERF-COMMANDS* := { **show** | **list** | **help** } 34 35 *NET-COMMANDS* := { **show** | **list** | **help** } 36 37 *FEATURE-COMMANDS* := { **probe** | **help** } 38 39DESCRIPTION 40=========== 41 *bpftool* allows for inspection and simple modification of BPF objects 42 on the system. 43 44 Note that format of the output of all tools is not guaranteed to be 45 stable and should not be depended upon. 46 47OPTIONS 48======= 49 -h, --help 50 Print short help message (similar to **bpftool help**). 51 52 -V, --version 53 Print version number (similar to **bpftool version**). 54 55 -j, --json 56 Generate JSON output. For commands that cannot produce JSON, this 57 option has no effect. 58 59 -p, --pretty 60 Generate human-readable JSON output. Implies **-j**. 61 62 -m, --mapcompat 63 Allow loading maps with unknown map definitions. 64 65 -n, --nomount 66 Do not automatically attempt to mount any virtual file system 67 (such as tracefs or BPF virtual file system) when necessary. 68 69 -d, --debug 70 Print all logs available, even debug-level information. This 71 includes logs from libbpf as well as from the verifier, when 72 attempting to load programs. 73 74SEE ALSO 75======== 76 **bpf**\ (2), 77 **bpf-helpers**\ (7), 78 **bpftool-prog**\ (8), 79 **bpftool-map**\ (8), 80 **bpftool-cgroup**\ (8), 81 **bpftool-feature**\ (8), 82 **bpftool-net**\ (8), 83 **bpftool-perf**\ (8), 84 **bpftool-btf**\ (8) 85
