Readers,
Basex772 jar file was installed into a directory /usr/local/basex
A symbolic link was created:
cat >> /usr/local/bin/basex java -jar /usr/local/basex/basex772.jar
In normal user home directory, basex started from command terminal, but the command line options are not active, e.g. 'basex -h' does not show the help file in the command terminal, but starts basex standalone.
Also command terminal 'basex -i /path/to/existing/xmlfile.xml' does not open the xml file, but starts basex.
