For the `bpftool prog dump { jited | xlated } ...` command, adding
`opcodes` keyword (to request opcodes to be printed) will have no effect
if `file FILE` (to write binary output to FILE) is provided.
The manual page and the help message to be displayed in the terminal
should reflect that, and indicate that these options should be mutually
exclusive.

DESCRIPTION
|
|
===========
|
|
**bpftool prog show** [*PROG*]
|
|
Show information about loaded programs. If *PROG* is
|
|
specified show information only about given program, otherwise
|
|
list all programs currently loaded on the system.
|
|
|
|
Output will start with program ID followed by program type and
|
|
zero or more named attributes (depending on kernel version).
|
|
|
|
**bpftool prog dump xlated** *PROG* [{ **file** *FILE* | **opcodes** }]
|
|
Dump eBPF instructions of the program from the kernel.
|
|
If *FILE* is specified image will be written to a file,
|
|
otherwise it will be disassembled and printed to stdout.
|
|
|
|
**opcodes** controls if raw opcodes will be printed.
|
|
|
|
**bpftool prog dump jited** *PROG* [{ **file** *FILE* | **opcodes** }]
|
|
Dump jited image (host machine code) of the program.
|
|
If *FILE* is specified image will be written to a file,
|
|
otherwise it will be disassembled and printed to stdout.
|
|
|
|
**opcodes** controls if raw opcodes will be printed.
|
|
|
|
**bpftool prog pin** *PROG* *FILE*
|
|
Pin program *PROG* as *FILE*.
|
|
|
|
Note: *FILE* must be located in *bpffs* mount.
|
|
|
|
**bpftool prog help**
|
|
Print short help message.
