   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

 463
 464 Verify the number using the code received via SMS or voice::
 465 signal-cli -u USERNAME verify CODE
 466
 467 Send a message to one or more recipients::
 468 signal-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
 469
 470 Pipe the message content from another process::
 471 uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
 472
 473 Create a group::
 474 signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]

 487
 488 Trust new key, after having verified it::
 489 signal-cli -u USERNAME trust -v SAFETY_NUMBER NUMBER
 490
 491 Trust new key, without having verified it. Only use this if you don't care about security::
 492 signal-cli -u USERNAME trust -a NUMBER
 493
 494 == Exit codes
 495 * *1*: Error is probably caused and fixable by the user
 496 * *2*: Some unexpected error
 497 * *3*: Server or IO error
 498 * *4*: Sending failed due to untrusted key
 499
 500 == Files
 501
 502 The password and cryptographic keys are created when registering and stored in the current users home directory, the directory can be changed with *--config*:
 503
 504 `$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
 505
 506 For legacy users, the old config directories are used as a fallback:
 507
 508     $HOME/.config/signal/
 509
 510     $HOME/.config/textsecure/
