# ls -lisa | less does the job
Thank you very much for the help!
Even somethimes I would prefer that after every keystrocke(enter key) the whole
visible part of Terminal would be "filled" with files/folders...
# ls -lisa | less on Catalina does infact fill the whole visible part of Terminal
with files/folders after pressing enter the first time, but after that, pressing
the enter-key for every additonal line is required...
Thanks!
