2.6.1 Passing Arguments to Executable Scripts

Note that when Octave is started from an executable script, the built-in function argv returns a cell array containing the command line arguments passed to the executable Octave script, not the arguments passed to the Octave interpreter on the ‘#!’ line of the script. For example, the following program will reproduce the command line that was used to execute the script, not ‘-qf’.

#! /bin/octave -qf
printf ("%s", program_name ());
arg_list = argv ();
for i = 1:nargin
  printf (" %s", arg_list{i});
endfor
printf ("\n");
