== Name
-signal-cli - A commandline and dbus interface for the Signal messenger
+signal-cli - A commandline interface for the Signal messenger
== Synopsis
-*signal-cli* [--config CONFIG] [-h | -v | -u USERNAME | --dbus | --dbus-system] command [command-options]
+*signal-cli* [--config CONFIG] [-h | -v | -a ACCOUNT | --dbus | --dbus-system] command [command-options]
== Description
It supports registering, verifying, sending and receiving messages.
For registering you need a phone number where you can receive SMS or incoming calls.
signal-cli was primarily developed to be used on servers to notify admins of important events.
-For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.
+For this use-case, it has a dbus and a JSON-RPC interface, that can be used to send messages from other programs.
For some functionality the Signal protocol requires that all messages have been received from the server.
-The `receive` command should be regularly executed. In daemon mode messages are continuously received.
+The `receive` command should be regularly executed.
+In daemon mode messages are continuously received.
== Options
*--verbose*::
Raise log level and include lib signal logs.
+*--log-file* LOG_FILE::
+Write log output to the given file.
+If `--verbose` is also given, the detailed logs will only be written to the log file.
+
*--config* CONFIG::
Set the path, where to store the config.
Make sure you have full read/write access to the given directory.
(Default: `$XDG_DATA_HOME/signal-cli` (`$HOME/.local/share/signal-cli`))
-*-u* USERNAME, *--username* USERNAME::
+*-a* ACCOUNT, *--account* ACCOUNT::
Specify your phone number, that will be your identifier.
The phone number must include the country calling code, i.e. the number must start with a "+" sign.
This flag must not be given for the `link` command.
It is optional for the `daemon` command.
-For all other commands it is only optional if there is exactly one local user in the
-config directory.
+For all other commands it is only optional if there is exactly one local user in the config directory.
+
+*--service-environment* ENVIRONMENT::
+Choose the server environment to use:
+
+- `live` (default)
+- `staging`
*--dbus*::
Make request via user dbus.
Make request via system dbus.
*-o* OUTPUT-MODE, *--output* OUTPUT-MODE::
-Specify if you want commands to output in either "plain-text" mode or in "json". Defaults to "plain-text"
+Specify if you want commands to output in either "plain-text" mode or in "json".
+Defaults to "plain-text"
+
+*--trust-new-identities* TRUST-MODE::
+Choose when to trust new identities:
+- `on-first-use` (default): Trust the first seen identity key from new users, changed keys must be verified manually
+- `always`: Trust any new identity key without verification
+- `never`: Don't trust any unknown identity key, every key must be verified manually
== Commands
Register a phone number with SMS or voice verification.
Use the verify command to complete the verification.
+If the account is just deactivated, the register command will just reactivate account, without requiring an SMS verification.
+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.
+If the account was deleted (with --delete-account) it cannot be reactivated.
+
*-v*, *--voice*::
The verification should be done over voice, not SMS.
*--captcha*::
The captcha token, required if registration failed with a captcha required error.
To get the token, go to https://signalcaptchas.org/registration/generate.html
-Check the developer tools for a redirect starting with signalcaptcha://
-Everything after signalcaptcha:// is the captcha token.
+For the staging environment, use: https://signalcaptchas.org/staging/registration/generate.html
+Check the developer tools for a redirect starting with signalcaptcha:// Everything after signalcaptcha:// is the captcha token.

Trust new key, after having verified it::
-signal-cli -u USERNAME trust -v SAFETY_NUMBER NUMBER
+signal-cli -a ACCOUNT trust -v SAFETY_NUMBER NUMBER
Trust new key, without having verified it. Only use this if you don't care about security::
-signal-cli -u USERNAME trust -a NUMBER
+signal-cli -a ACCOUNT trust -a NUMBER
== Exit codes
+
* *1*: Error is probably caused and fixable by the user
* *2*: Some unexpected error
* *3*: Server or IO error
`$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
