阅读README文件了解软件的安装方法
查看install-Linux-tar.txt（相当于README）文件发现启动console的方法：
Linux Installation Instructions
------------------------------------------------------------------------------
1. Unpack the IntelliJ IDEA distribution archive that you downloaded to
where you wish to install the program. We will refer to this destination
location as your {installation home} below.
2. Open a console and cd into "{installation home}/bin" and type:
./idea.sh
to start the application. As a side effect, this will initialize various
configuration files in the ~/.IntelliJIdea2019.1 directory.
3. [OPTIONAL] Add "{installation home}/bin" to your PATH environment
variable so that you may start IntelliJ IDEA from any directory.
4. [OPTIONAL] To adjust the value of the JVM heap size, create
~/.IntelliJIdea2019.1/config/idea.vmoptions (or idea64.vmoptions
if using a 64-bit JDK), and set the -Xms and -Xmx parameters. To see how
to do this, you can reference the vmoptions file under
"{installation home}/bin" as a model.
注意：不能直接找到bin/idea.sh 打开，需要在终端中执行命令才会有效，进而才能启动后续的安装步骤。
