Show the LiteSpeed or OpenLiteSpeed version

harmless rootLiteSpeeddebian, ubuntu
root@server
/usr/local/lsws/bin/lshttpd -v

Runs the server binary with the version option and prints the product name and version number. Important for knowing the current state before an update or for matching security advisories to a version.

Note: The file /usr/local/lsws/VERSION also contains the installed version in plain text.

Open question before approval: Prüfen, ob lshttpd -v bei OpenLiteSpeed und bei LiteSpeed Enterprise gleichermaßen die Version ausgibt. Alternativ steht die Version in /usr/local/lsws/VERSION.
