   8 == Name

  10 signal-cli - A commandline and dbus interface for the Signal messenger
  11
  12 == Synopsis
  13
  14 *signal-cli* [--config CONFIG] [-h | -v | -u USERNAME | --dbus | --dbus-system] command [command-options]
  15
  16 == Description
  17
  18 signal-cli is a commandline interface for libsignal-service-java.
  19 It supports registering, verifying, sending and receiving messages.
  20 For registering you need a phone number where you can receive SMS or incoming calls.
  21 signal-cli was primarily developed to be used on servers to notify admins of important events.
  22 For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.
  23
  24 For some functionality the Signal protocol requires that all messages have been received from the server.
  25 The `receive` command should be regularly executed. In daemon mode messages are continuously received.
  26

 443 signal-cli -u USERNAME verify CODE
 444
 445 Send a message to one or more recipients::
 446 signal-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
 447
 448 Pipe the message content from another process::
 449 uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
 450
 451 Create a group::
 452 signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]

 465
 466 Trust new key, after having verified it::
 467 signal-cli -u USERNAME trust -v SAFETY_NUMBER NUMBER
 468
 469 Trust new key, without having verified it. Only use this if you don't care about security::
 470 signal-cli -u USERNAME trust -a NUMBER
 471
 472 == Exit codes
 473 * *1*: Error is probably caused and fixable by the user
 474 * *2*: Some unexpected error
 475 * *3*: Server or IO error
 476 * *4*: Sending failed due to untrusted key
 477
 478 == Files
 479
 480 The password and cryptographic keys are created when registering and stored in the current users home directory, the directory can be changed with *--config*:
 481
 482 `$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
 483
 484 For legacy users, the old config directories are used as a fallback:
 485
 486     $HOME/.config/signal/
 487
 488     $HOME/.config/textsecure/
