How do I check the prometheus version?

I'm running two servers with Ubuntu and one of them has grafana and prometheus running on it. I'm trying to rebuild the same environment on the other server however I fail to find the version of it. Searching with find / prometheus* also didn't have any result.

What should I do?

As suggested, with the command find / -iname '*prometheus*', the result included among other things:

/opt/prometheus/prometheus-0.20.0.linux-amd64
/opt/prometheus/prometheus-0.20.0.linux-amd64/prometheus.yml
/opt/prometheus/prometheus-0.20.0.linux-amd64/prometheus

Which shows the version is 0.20.0. Thanks a lot for the help.

Also, you can use ./prometheus -version in the folder to find the detail of the version:

prometheus, version 0.20.0 (branch: master, revision: aeab25c) build user: root@77050118f904 build date: 20160616-08:38:14 go version: go1.6.2

Perhaps it has changed in the last few years but I had to use two hyphens before version:

./prometheus --version

not

./prometheus -version
