Linux Mint 21.3 Cinnamon 4 years later. Still works with this text file syntax: ~$ morse -BSew5 -F15 -f750 < ~/cw/cw.txt See the output of man morse for details. I could not make -C STRING work as it should. The remainder of my review from 2020 follows: This reads the text from a text document located at ~/cw/cw.txt and converts it into Morse code at the specified speed. This example runs 5WPM overall speed with character speed at 15WPM Farnsworth. Place this command in a Bash shell script, make it executable and !Important for LM 19.1 MATE: place the script in ~/.config/caja/scripts and then find scripts in any right-click menu and run your script from the side menu. That way the whole process can be run from the graphic user interface!
