# 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: ```bash $ 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. ```bash $ openssl version -v LibreSSL 2.8.3 ``` See `man openssl` for more details.
