How do I find out what version of SQL Server for Linux I have?

How do I find out what version of SQL I am running if I can't connect to it because it's crashing? Is there something like --version

$ ./sqlservr --version
Dump collecting thread [8633] hit exception [6]. Exiting.

Using dpkg

dpkg -l | grep -i mssql-server
ii  mssql-server                              14.0.3008.27-1                              amd64        Microsoft SQL Server Relational Database Engine

Using PAL_PROGRAM_INFO=1

You can set the undocumented environmental variable PAL_PROGRAM_INFO for a lot of information,

PAL_PROGRAM_INFO=1 ./sqlservr
