.SH DESCRIPTION
.INDENT 0.0
.INDENT 3.5
\fIbpftool\fP allows for inspection and simple modification of BPF objects
on the system.
.sp
Note that format of the output of all tools is not guaranteed to be
stable and should not be depended upon.

.SH OPTIONS
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.TP
.B  \-h\fP,\fB  \-\-help
Print short help message (similar to \fBbpftool help\fP).
.TP
.B  \-V\fP,\fB  \-\-version
Print bpftool\(aqs version number (similar to \fBbpftool version\fP), the
number of the libbpf version in use, and optional features that were
included when bpftool was compiled. Optional features include linking
against LLVM or libbfd to provide the disassembler for JIT\-ted
programs (\fBbpftool prog dump jited\fP) and usage of BPF skeletons
(some features like \fBbpftool prog profile\fP or showing pids
associated to BPF objects may rely on it).
.TP
.B  \-j\fP,\fB  \-\-json
Generate JSON output. For commands that cannot produce JSON, this
option has no effect.
.TP
.B  \-p\fP,\fB  \-\-pretty
Generate human\-readable JSON output. Implies \fB\-j\fP\&.
.TP
.B  \-d\fP,\fB  \-\-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.
.UNINDENT
.INDENT 0.0
.TP
.B  \-m\fP,\fB  \-\-mapcompat
Allow loading maps with unknown map definitions.
.TP
.B  \-n\fP,\fB  \-\-nomount
Do not automatically attempt to mount any virtual file system
(such as tracefs or BPF virtual file system) when necessary.
