What can I do with testssl.sh command?

How to disable DNS lookup in testssl.sh?
You might want to keep logs for later analysis, testssl.sh has the –log (store log file in the current directory) or –logfile (specify log file location) option for that. To disable DNS lookup, which can increase test speeds, use the -n flag.
How is port 465 tested in testssl.sh?
The ports can be different and will be tested by testssl.sh according to common practice in the internet, i.e. if nmap shows in its output an open port 25, automatically -t smtp will be added before the URI whereas port 465 will be treated as a plain TLS/SSL port, not requiring an STARTTLS SMTP handshake upfront.
Is there a command line tool for testing SSL?
testssl.sh is a free and open-source, feature-rich command-line tool used for checking TLS/SSL encryption enabled services for supported ciphers, protocols, and some cryptographic flaws, on Linux/BSD servers. It can be run on macOS X and Windows using MSYS2 or Cygwin.
