I think we can call this bug report resolved, reporter seems satisfied with using the ECHO_SCRIPTS value (1) instead of ECHO_CMD_LINE (4) with current versions of Octave to show input from non-interactive script text.

Using

octave -qfx test.m

delivers much more output since all the functions called by octave are displayed, too. I use octave as computing server and just want to see the user input echoed.

But the solution with "echo_executing_commands (1);" and

octave -qf test.m

works as in 3.6.x. Thanks a lot.

Confirmed, only applies to Octave commands sent to the interpreter on stdin. The correct behavior persists if you run your example as

octave -qfx test.m

telling Octave to run the m-file instead of reading it from the standard input stream. And either using the -x command-line option as shown above, or changing your script to set the echo_executing_commands value to 1 instead of 4.

The attached test.m called from the command line via  "octave -qf < test.m" results in 3.8.0 & 3.8.1:

  ans =  4
  ans =

     17   24    1    8   15
     23    5    7   14   16
      4    6   13   20   22
     10   12   19   21    3
     11   18   25    2    9

and in 3.6.4:

  + echo_executing_commands()
  ans =  4
  + magic(5)
  ans =

     17   24    1    8   15
     23    5    7   14   16
      4    6   13   20   22
     10   12   19   21    3
     11   18   25    2    9

  + echo_executing_commands(0);

If I start octave 3.8.1 and type in the command by hand then I get the same result as in 3.6.4.

The problem might be with the function

void octave_base_reader::do_input_echo (const std::string& input_string) const

in the file libinterp/corefcn/input.cc .

When typing in the commands within octave the function is called, when calling "octave -qf < test.m" the function seems not be called.
