   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

 436 signal-cli -u USERNAME verify CODE
 437
 438 Send a message to one or more recipients::
 439 signal-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
 440
 441 Pipe the message content from another process::
 442 uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
 443
 444 Create a group::
 445 signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
 446

 448 signal-cli -u USERNAME updateGroup -g GROUP_ID -m "NEW_MEMBER"
 449

 451 signal-cli -u USERNAME quitGroup -g GROUP_ID
 452
 453 Send a message to a group::
 454 signal-cli -u USERNAME send -m "This is a message" -g GROUP_ID
 455
 456 Trust new key, after having verified it::
 457 signal-cli -u USERNAME trust -v SAFETY_NUMBER NUMBER
 458
 459 Trust new key, without having verified it. Only use this if you don't care about security::
 460 signal-cli -u USERNAME trust -a NUMBER
 461
 462 == Exit codes
 463 * *1*: Error is probably caused and fixable by the user
 464 * *2*: Some unexpected error
 465 * *3*: Server or IO error
 466 * *4*: Sending failed due to untrusted key
 467
 468 == Files
 469
 470 The password and cryptographic keys are created when registering and stored in the current users home directory, the directory can be changed with *--config*:
 471
 472 `$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
 473
 474 For legacy users, the old config directories are used as a fallback:
 475
 476     $HOME/.config/signal/
 477
 478     $HOME/.config/textsecure/
