     FILE.  For example,           exec ("ls" "-l")      will run 'ls' and 
return you to your shell prompt.
*******************************
          exec ("ls" "-l")
should be
          exec ("ls", "-l")
(missing comma) BTW, octave termination of octave by exec ("ls", "-l") is an 
expected behavior.
However, octave erroneously terminates on octave 4.0.2 (32 and 64 bit)
I attached message from Windows. (Sorry it is written in Japanese.)

Translation
 Octave-cli is terminated.
 Problems occurred and program does not work correctly.
 Program is terminated by windows system.
 If there is a solution, it is reported from windows system.

    there is an indication of going through an emergency shutdown which
    is incorrect, although the eventual shell command is executed
    correctly.  See below
