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.
40 *--log-file* LOG_FILE::
41 Write log output to the given file.
42 If `--verbose` is also given, the detailed logs will only be written to the log file.
45 Set the path, where to store the config.
46 Make sure you have full read/write access to the given directory.
47 (Default: `$XDG_DATA_HOME/signal-cli` (`$HOME/.local/share/signal-cli`))
49 *-a* ACCOUNT, *--account* ACCOUNT::
50 Specify your phone number, that will be your identifier.
51 The phone number must include the country calling code, i.e. the number must start with a "+" sign.
53 This flag must not be given for the `link` command.
54 It is optional for the `daemon` command.
55 For all other commands it is only optional if there is exactly one local user in the config directory.
57 *--service-environment* ENVIRONMENT
58 Choose the server environment to use:
63 Make request via user dbus.
66 Make request via system dbus.
68 *-o* OUTPUT-MODE, *--output* OUTPUT-MODE::
69 Specify if you want commands to output in either "plain-text" mode or in "json".
70 Defaults to "plain-text"
72 *--trust-new-identities* TRUST-MODE::
73 Choose when to trust new identities:
74 - `on-first-use` (default): Trust the first seen identity key from new users, changed keys must be verified manually
75 - `always`: Trust any new identity key without verification
76 - `never`: Don't trust any unknown identity key, every key must be verified manually
82 Register a phone number with SMS or voice verification.
83 Use the verify command to complete the verification.
85 If the account is just deactivated, the register command will just reactivate account, without requiring an SMS verification.
86 By default the unregister command just deactivates the account, in which case it can be reactivated without sms verification if the local data is still available.
87 If the account was deleted (with --delete-account) it cannot be reactivated.
90 The verification should be done over voice, not SMS.
93 The captcha token, required if registration failed with a captcha required error.
94 To get the token, go to https://signalcaptchas.org/registration/generate.html
95 Check the developer tools for a redirect starting with signalcaptcha:// Everything after signalcaptcha:// is the captcha token.
99 Verify the number using the code received via SMS or voice.
102 The verification code.
104 *-p* PIN, *--pin* PIN::
105 The registration lock PIN, that was set by the user.
106 Only required if a PIN was set.
110 Disable push support for this device, i.e. this device won't receive any more messages.
111 If this is the master device, other users can't send messages to this number anymore.
112 Use "updateAccount" to undo this.
113 To remove a linked device, use "removeDevice" from the master device.
116 Delete account completely from server.
117 Cannot be undone without loss.
118 You will have to be readded to each group.
120 CAUTION: Only delete your account if you won't use this number again!
124 Update the account attributes on the signal server.
125 Can fix problems with receiving messages.
127 *-n* NAME, *--device-name* NAME::
