lightning-cli -- Control lightning daemon
=========================================

SYNOPSIS
--------

**lightning-cli** \[*OPTIONS*\] *command*…

DESCRIPTION
-----------

**lightning-cli** sends commands to the lightning daemon.

OPTIONS
-------

 **--lightning-dir**=*DIR*
Set the directory for the lightning daemon we’re talking to; defaults to
*$HOME/.lightning*.

 **--conf**=*PATH*
Sets configuration file (default: **lightning-dir**/*config* ).

 **--network**=*network*
 **--mainnet**
 **--testnet**
 **--signet**
Sets network explicitly.

 **--rpc-file**=*FILE*
Named pipe to use to talk to lightning daemon: default is
*lightning-rpc* in the lightning directory.

 **--keywords**/**-k**
Use format *key*=*value* for parameters in any order

 **--order**/**-o**
Follow strictly the order of parameters for the command

 **--json**/**-J**
Return result in JSON format (default unless *help* command,
or result contains a `format-hint` field).

 **--raw**/**-R**
Return raw JSON directly as lightningd replies; this can be faster for
large requests.

 **--human-readable**/**-H**
Return result in human-readable output.

 **--flat**/**-F**
Return JSON result in flattened one-per-line output, e.g. `{ "help":
[ { "command": "check" } ] }` would become `help[0].command=check`.
This is useful for simple scripts which want to find a specific output
field without parsing JSON.

 **--help**/**-h**
Pretty-print summary of options to standard output and exit.  The format can
be changed using -F, -R, -J, -H etc.

 **--version**/**-V**
Print version number to standard output and exit.

 **allow-deprecated-apis**=*BOOL*
Enable deprecated options. It defaults to *true*, but you should set
it to *false* when testing to ensure that an upgrade won’t break your
configuration.

COMMANDS
--------

*lightning-cli* simply uses the JSON RPC interface to talk to
*lightningd*, and prints the results. Thus the commands available depend
entirely on the lightning daemon itself.

ARGUMENTS
---------

Arguments may be provided positionally or using *key*=*value* after the
command name, based on either **-o** or **-k** option. Arguments may be
integer numbers (composed entirely of digits), floating-point numbers
(has a radix point but otherwise composed of digits), *true*, *false*,
or *null*. Other arguments are treated as strings.

Some commands have optional arguments. You may use *null* to skip
optional arguments to provide later arguments.

EXAMPLES
--------

BUGS
----

This manpage documents how it should work, not how it does work. The
pretty printing of results isn’t pretty.
