   9 == Name
  10
  11 signal-cli - A commandline interface for the Signal messenger
  12

  16
  17 == Description
  18
  19 signal-cli is a commandline interface for libsignal-service-java.
  20 It supports registering, verifying, sending and receiving messages.
  21 For registering you need a phone number where you can receive SMS or incoming calls.
  22 signal-cli was primarily developed to be used on servers to notify admins of important events.
  23 For this use-case, it has a dbus and a JSON-RPC interface, that can be used to send messages from other programs.
  24
  25 For some functionality the Signal protocol requires that all messages have been received from the server.
  26 The `receive` command should be regularly executed.
  27 In daemon mode messages are continuously received.

 103 Check the developer tools for a redirect starting with signalcaptcha:// Everything after signalcaptcha:// is the captcha token.

 688 == Examples
 689
 690 Register a number (with SMS verification)::
 691 signal-cli -a ACCOUNT register
 692
 693 Verify the number using the code received via SMS or voice::

 697 signal-cli -a ACCOUNT send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
 698
 699 Pipe the message content from another process::
 700 uname -a | signal-cli -a ACCOUNT send --message-from-stdin [RECIPIENT [RECIPIENT ...]]
 701
 702 Create a group::
 703 signal-cli -a ACCOUNT updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
 704
 705 Add member to a group::
 706 signal-cli -a ACCOUNT updateGroup -g GROUP_ID -m "NEW_MEMBER"
 707
 708 Accept a group invitation::
 709 signal-cli -a ACCOUNT updateGroup -g GROUP_ID
 710
 711 Leave a group::
 712 signal-cli -a ACCOUNT quitGroup -g GROUP_ID
 713
 714 Send a message to a group::
 715 signal-cli -a ACCOUNT send -m "This is a message" -g GROUP_ID
 716
 717 Trust new key, after having verified it::
 718 signal-cli -a ACCOUNT trust -v SAFETY_NUMBER NUMBER
 719
 720 Trust new key, without having verified it. Only use this if you don't care about security::
 721 signal-cli -a ACCOUNT trust -a NUMBER
 722
