   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.

 651
 652 *--tcp [HOST:PORT]*::
 653 Export a JSON-RPC interface on a TCP socket (default localhost:7583).

 671 == Examples
 672
 673 Register a number (with SMS verification)::
 674 signal-cli -a ACCOUNT register
 675
 676 Verify the number using the code received via SMS or voice::
 677 signal-cli -a ACCOUNT verify CODE
 678
 679 Send a message to one or more recipients::
 680 signal-cli -a ACCOUNT send -m "This is a message" [RECIPIENT [RECIPIENT ...]] [-a [ATTACHMENT [ATTACHMENT ...]]]
 681
 682 Pipe the message content from another process::
 683 uname -a | signal-cli -a ACCOUNT send --message-from-stdin [RECIPIENT [RECIPIENT ...]]
 684
 685 Create a group::
 686 signal-cli -a ACCOUNT updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
 687
 688 Add member to a group::
 689 signal-cli -a ACCOUNT updateGroup -g GROUP_ID -m "NEW_MEMBER"
 690
 691 Accept a group invitation::
 692 signal-cli -a ACCOUNT updateGroup -g GROUP_ID
 693
 694 Leave a group::
 695 signal-cli -a ACCOUNT quitGroup -g GROUP_ID
 696
 697 Send a message to a group::
 698 signal-cli -a ACCOUNT send -m "This is a message" -g GROUP_ID
 699
 700 Trust new key, after having verified it::
 701 signal-cli -a ACCOUNT trust -v SAFETY_NUMBER NUMBER
 702
 703 Trust new key, without having verified it. Only use this if you don't care about security::
 704 signal-cli -a ACCOUNT trust -a NUMBER
 705
 706 == Exit codes

 708 * *1*: Error is probably caused and fixable by the user
 709 * *2*: Some unexpected error

 711 * *4*: Sending failed due to untrusted key
 712
 713 == Files
 714
 715 The password and cryptographic keys are created when registering and stored in the current users home directory, the directory can be changed with *--config*:
 716
 717 `$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
