-# textsecure-cli

-textsecure-cli is a commandline interface for [libtextsecure-java](https://github.com/WhisperSystems/libtextsecure-java). It supports registering, verifying, sending and receiving messages. However receiving messages currently doesn't work, because libtextsecure-java [does not yet support registering for the websocket support](https://github.com/WhisperSystems/libtextsecure-java/pull/5). For registering you need a phone number where you can receive SMS or incoming calls.
-It is primarily intented to be used on servers to notify admins of important events.
+signal-cli is a commandline interface for [libsignal-service-java](https://github.com/WhisperSystems/libsignal-service-java). It supports registering, verifying, sending and receiving messages.
+To be able to link to an existing Signal-Android/signal-cli instance, signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java does not yet support [provisioning as a slave device](https://github.com/WhisperSystems/libsignal-service-java/pull/21).
+For registering you need a phone number where you can receive SMS or incoming calls.
+signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a dbus interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)), that can be used to send messages from any programming language that has dbus bindings.

 
 

-## Usage
+## Installation
+
+You can [build signal-cli](#building) yourself, or use the [provided binary files](https://github.com/AsamK/signal-cli/releases/latest), which should work on Linux, macOS and Windows. For Arch Linux there is also a [package in AUR](https://aur.archlinux.org/packages/signal-cli/) and there is a [FreeBSD port](https://www.freshports.org/net-im/signal-cli) available as well.
+
+System requirements:
+- at least Java Runtime Environment (JRE) 11
+- native libraries: libzkgroup, libsignal-client
+
+  Those are bundled for x86_64 Linux, for other systems/architectures see: [Provide native lib for libsignal](https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal)

 
 

-usage: textsecure-cli [-h] -u USERNAME {register,verify,send,receive} ...
+### Install system-wide on Linux
+See [latest version](https://github.com/AsamK/signal-cli/releases).
+```sh
+export VERSION=<latest version, format "x.y.z">
+wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}".tar.gz
+sudo tar xf signal-cli-"${VERSION}".tar.gz -C /opt
+sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/
+```
+You can find further instructions on the Wiki:

+- [DBus Service](https://github.com/AsamK/signal-cli/wiki/DBus-service)

 
 

-* Register a number
+## Usage
+
+For a complete usage overview please read the [man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli.1.adoc) and the [wiki](https://github.com/AsamK/signal-cli/wiki).

 
 

-        textsecure-cli -u USERNAME register
+Important: The USERNAME is your phone number in international format and must include the country calling code. Hence it should start with a "+" sign. (See [Wikipedia](https://en.wikipedia.org/wiki/List_of_country_calling_codes) for a list of all country codes.)

 
 

-* Register a number with voice verification
+* Register a number (with SMS verification)

 
 

-        textsecure-cli -u USERNAME register -v
+        signal-cli -u USERNAME register
+        
+  You can register Signal using a land line number. In this case you can skip SMS verification process and jump directly to the voice call verification by adding the --voice switch at the end of above register command.

 
 

-* Verify the number using the code received via SMS
+* Verify the number using the code received via SMS or voice, optionally add `--pin PIN_CODE` if you've added a pin code to your account

 
 

-        textsecure-cli -u USERNAME verify CODE
+        signal-cli -u USERNAME verify CODE

 
 

-* Send a message to one or more recipients
+* Send a message

 
 

-        textsecure-cli -u USERNAME send -m "This is a message" [RECIPIENT [RECIPIENT ...]]
+        signal-cli -u USERNAME send -m "This is a message" RECIPIENT

 
 * Pipe the message content from another process.
 
 
 * Pipe the message content from another process.
 

-        uname -a | textsecure-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
+        uname -a | signal-cli -u USERNAME send RECIPIENT
+        
+* Receive messages
+
+        signal-cli -u USERNAME receive

+### Building a native binary with GraalVM (EXPERIMENTAL)
+
+It is possible to build a native binary with [GraalVM](https://www.graalvm.org).
+This is still experimental and will not work in all situations.
+
+1. [Install GraalVM and setup the enviroment](https://www.graalvm.org/docs/getting-started/#install-graalvm)
+2. [Install prerequisites](https://www.graalvm.org/reference-manual/native-image/#prerequisites)
+3. Execute Gradle:
+
+        ./gradlew assembleNativeImage
+  
+   The binary is available at *build/native-image/signal-cli*
