11 signal-cli - A commandline and dbus interface for the Signal messenger
15 *signal-cli* [--config CONFIG] [-h | -v | -a ACCOUNT | --dbus | --dbus-system] command [command-options]
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 interface, that can be used to send messages from any programming language that has dbus bindings.
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.
32 Show help message and quit.
35 Print the version and quit.
38 Raise log level and include lib signal logs.
41 Set the path, where to store the config.
42 Make sure you have full read/write access to the given directory.
43 (Default: `$XDG_DATA_HOME/signal-cli` (`$HOME/.local/share/signal-cli`))
45 *-a* ACCOUNT, *--account* ACCOUNT::
46 Specify your phone number, that will be your identifier.
47 The phone number must include the country calling code, i.e. the number must start with a "+" sign.
49 This flag must not be given for the `link` command.
50 It is optional for the `daemon` command.
51 For all other commands it is only optional if there is exactly one local user in the config directory.
54 Make request via user dbus.
57 Make request via system dbus.
59 *-o* OUTPUT-MODE, *--output* OUTPUT-MODE::
60 Specify if you want commands to output in either "plain-text" mode or in "json".
61 Defaults to "plain-text"
63 *--trust-new-identities* TRUST-MODE::
64 Choose when to trust new identities:
65 - `on-first-use` (default): Trust the first seen identity key from new users, changed keys must be verified manually
66 - `always`: Trust any new identity key without verification
67 - `never`: Don't trust any unknown identity key, every key must be verified manually
73 Register a phone number with SMS or voice verification.
74 Use the verify command to complete the verification.
77 The verification should be done over voice, not SMS.
80 The captcha token, required if registration failed with a captcha required error.
81 To get the token, go to https://signalcaptchas.org/registration/generate.html
82 Check the developer tools for a redirect starting with signalcaptcha:// Everything after signalcaptcha:// is the captcha token.
86 Verify the number using the code received via SMS or voice.
89 The verification code.
91 *-p* PIN, *--pin* PIN::
92 The registration lock PIN, that was set by the user.
93 Only required if a PIN was set.
97 Disable push support for this device, i.e. this device won't receive any more messages.
98 If this is the master device, other users can't send messages to this number anymore.
99 Use "updateAccount" to undo this.
100 To remove a linked device, use "removeDevice" from the master device.
103 Delete account completely from server.
104 Cannot be undone without loss.
105 You will have to be readded to each group.
107 CAUTION: Only delete your account if you won't use this number again!
111 Update the account attributes on the signal server.
