11 signal-cli - A commandline 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 and a JSON-RPC interface, that can be used to send messages from other programs.
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:
64 Make request via user dbus.
67 Make request via system dbus.
69 *-o* OUTPUT-MODE, *--output* OUTPUT-MODE::
70 Specify if you want commands to output in either "plain-text" mode or in "json".
71 Defaults to "plain-text"
73 *--trust-new-identities* TRUST-MODE::
74 Choose when to trust new identities:
75 - `on-first-use` (default): Trust the first seen identity key from new users, changed keys must be verified manually
76 - `always`: Trust any new identity key without verification
77 - `never`: Don't trust any unknown identity key, every key must be verified manually
83 Register a phone number with SMS or voice verification.
84 Use the verify command to complete the verification.
86 If the account is just deactivated, the register command will just reactivate account, without requiring an SMS verification.
87 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.
88 If the account was deleted (with --delete-account) it cannot be reactivated.
91 The verification should be done over voice, not SMS.
94 The captcha token, required if registration failed with a captcha required error.
95 To get the token, go to https://signalcaptchas.org/registration/generate.html
96 For the staging environment, use: https://signalcaptchas.org/staging/registration/generate.html
97 Check the developer tools for a redirect starting with signalcaptcha:// Everything after signalcaptcha:// is the captcha token.
101 Verify the number using the code received via SMS or voice.
104 The verification code.
106 *-p* PIN, *--pin* PIN::
107 The registration lock PIN, that was set by the user.
108 Only required if a PIN was set.
112 Disable push support for this device, i.e. this device won't receive any more messages.
113 If this is the master device, other users can't send messages to this number anymore.
114 Use "updateAccount" to undo this.
115 To remove a linked device, use "removeDevice" from the master device.
118 Delete account completely from server.
119 Cannot be undone without loss.
120 You will have to be readded to each group.
122 CAUTION: Only delete your account if you won't use this number again!
124 === deleteLocalAccountData
126 Delete all local data for this account.
127 Data should only be deleted if the account is unregistered.
129 CAUTION: This cannot be undone.
131 *--ignore-registered*::
132 Delete the account data even though the account is still registered on the Signal servers.
136 Update the account attributes on the signal server.
137 Can fix problems with receiving messages.

168 Remove the registration lock pin.
172 Link to an existing device, instead of registering a new number.
173 This shows a "sgnl://linkdevice?uuid=..." URI.
174 If you want to connect to another signal-cli instance, you can just use this URI.
175 If you want to link to an Android/iOS device, create a QR code with the URI (e.g. with qrencode) and scan that in the Signal app.
