Check The Installed OpenSSL Version

Typically with command line tools, I can use a --version or -v flag with the command to get it to output the current version. This is not the case with openssl.

When I do this:

$ openssl --version

I get an Invalid Command message and then a bunch of subcommands are displayed.

One of those subcommands listed under Standard Commands is the version command. This is what I can use to list the version.

$ openssl version -v
LibreSSL 2.8.3

See man openssl for more details.
