I'm using Ubuntu system. To run MATLAB script at launch, I can type matlab -nodesktop -r "run ./my_program.m".
How can I achieve the same function on Octave, like octave --no-gui -some_command?
I've read this post and this post. They did not answer my question.
As mentioned in one of the comment, one solution is:
octave --persist my_program.m
Currently looks like it is enough to say for script (not plain function)
octave my_program.m
Also if you have octave installed in your path you could and in the beginning of script as the first line the desired interpreter (works for python, bash, whatever), for example for default location :
#!/usr/bin/octave
and you can run them without even adding the octave in front... just the script name....
For Windows users:
I see it's a bit harder, since there's no "octave.exe" file.
I do have:
"C:\Program Files\GNU Octave\Octave-6.4.0\mingw64\bin\octave-cli-6.4.0.exe"
which works after adding both parent directories
"C:\Program Files\GNU Octave\Octave-6.4.0\mingw64\bin"
and
"C:\Program Files\GNU Octave\Octave-6.4.0\mingw64"
to PATH.
All this happens automatically in the startup script which is the normal entry point of the SW:
"C:\Program Files\GNU Octave\Octave-6.4.0\octave.vbs"
Finaly, after adding all to path I run it like this:
"C:\Program Files\GNU Octave\Octave-6.4.0\mingw64\bin\octave-cli-6.4.0.exe" "C:\MatlabScripts\matlabScript1.m" c:\temp\myCuteImage [example for prm]

I am running a MATLAB script from the Windows command prompt:
"C:\Program Files\MATLAB\R2014B\bin\matlab" -nodisplay -nosplash -nodesktop -wait -r "test.m"
The test.m is simple:
function test
disp('Hello!');
The output is displayed in the Matlab Command Window. Is there any way how I can force output to the windows prompt?
Use the command line option -log when you call Matlab from the command line (or any other shell or batch (e.g. cmd or bat) script).
It isn't documented as of Matlab 2017b, but it works.
Side note: -nodisplay isn't supported in the Windows version of Matlab, but if you want to prevent it from displaying figures, use -noFigureWindows instead.
Since R2019b, there is a new command line option, -batch, which redirects the output to the command line and handles other stuff for batch processing. See the documentation for Windows.
matlab -batch "statement to run"
This starts MATLAB without the desktop or splash screen, logs all output to stdout and stderr, exits automatically when the statement completes, and provides an exit code reporting success or error.
I don't know of a way to do it in Windows to get Matlab to actually run in the DOS window which is what you would need for the display to be written in it. (FYI: You can in LINUX - but I assume you need to run in Windows).
For running in Matlab you have 2 alternatives that I can think of:
-logfile FILE on launch which will record all output to a FILE you specify - however how and when the file is written to disk is controlled by Matlab and I haven't tested to see - if your code doesn't do much it might only be written on Matlab exit.
diary FILE in your Matlab command, i.e. -r "diary FILE.TXT; test.m; diary OFF" - this is similar to above - but uses the diary function.
However you can get what you want if you can run your code compiled (I know thats a big if as you may not have the compiler - or if you regularly want to update test.m this is not the most efficient...
When you run a compiled code from a DOS prompt all the terminal messages are written to the DOS prompt. One thing I'd advise if this is suitable is to delete the "splash.png" file from your installation directory to avoid the splash screen displaying when you run from the DOS as its (probably) not needed.
I have found a solution at:

I will replicate it here for convenience.
First I need to modify the matlab script to output to a text file:
function test
fid=fopen('output.txt','w');
fprintf(fid,'Hello!');
fclose(fid);
Then I should run the Matlab using a bat file with one additional command to display the contents of the output.txt:
"C:\Program Files\MATLAB\R2014B\bin\matlab" -nodisplay -nosplash -nodesktop -wait -r "test.m"
type output.txt
The type command will display the contents of 'output.txt' in the command window. So answer from #matlabgui was almost there. Thank you.
It is not a very elegant solution, but it works.

I have a startup Matlab script startup.m under
C:\SVN\myscripts\StartupScript
The script sets up paths and does some subsequent script calling successfully.
However, i created another file callMat.m in the same folder that just displays some data. When i run it from Matlab GUI, it works fine.
Howeever, calling it from cmd.exe,like below:
C:\Program Files\MATLAB\R2013b\bin\matlab.exe" -nosplash -nodesktop -wait -r "callMat"
I found that it opens Matlab command line and then
it first executes startup.m and then callMat.m .
Is this expected behavior, and if yes Why?
Thanks
sedy
Yes, this is expected behaviour. MATLAB executes startup.m when it starts up, whether it's started in the usual way, or whether it's started from the command line with -r and a command.
startup.m on your Matlab path is executed on startup.
I can find no description on the Matlab website suggesting that command line starting is any different.
In conclusion, it seems very likely this is expected behaviour. The documentation page here gives some suggestions as to the different places to put different options. In particular, it suggests that you:
Use startup.m to modify the default search path, predefine variables
in your workspace, or define defaults for graphics objects.
I have a executable that when double clicked opens in a command line window.
Now there is a input file (i.e named "sphere_15000.inp") in the same directory where the executable apame_win64.exe is located. So we can inter the file name in the command line.
The question is how this can be done from mathematica front end? With the RunThrough command I tried to do it with no avail.
RunThrough["Executable Location", "sphere_15000"]
Do I need to put this file location in my Windows 7 environment path variable? Hope for some suggestion in this regard.
UPDATE
Found a solution to my problem.
First set the Mathematica directory to the folder where the executable is located.
path="C:\Users\FlowCrusher\Desktop\CUSP solver\Apame_build_2011_01_09\solver";
SetDirectory[path];
Then use the following style of input.
Run["\"\"apame_win64.exe\" \"input\"\""]
Here "apame_win64.exe" is the executable one want to run and "input" is the input file for the executable. This solves the problem. But a new item in the wishlist.
Is there a way to hide the console window in the background?
Here is how it looks on my screen.
As Chris suggested if we use minimized console in the Run command we get a minimized window but the program does not execute.
I hope that a solution exists.
BR
Yes, you might put the folder of you executable into the Path variable, or provide the full path name.
However, RunThrough seems to have been superseeded (on Windows) by
Import["!command ","Text"], which will execute command and read the comaand line output into Matheamtica as a string.
E.g.:
Export["testit.txt", "bla", "Text"];
Import["!dir" <> " testit* > dir.log", "Text"];
FilePrint["dir.log"]
--
Otherwise, I also had good results in the past using NETLink (not sure if WScript.shell
still works on Windows7/8 or if one should use something else).
Emulating Run (RunThrough is not really needed I think):
Run2[cmd_String] := Module[{shell},
Switch[$OperatingSystem,
"Windows",
Needs["NETLink`"];
shell = NETLink`CreateCOMObject["WScript.shell"];
shell # run[cmd,0,True],
"Unix",
Run # cmd,
"MacOSX",
Run # cmd ] ];
Can you run your application with input from a basic command window instead of the application console? This might be the form of command you would need:
apame_win64 -input sphere_15000.inp
or simply
apame_win64 sphere_15000.inp
You can probably check the available switches by running apame_win64 -help
A multi-part command can be run from Mathematica, e.g.
Run["type c:\\temp\\test.txt"]
Alternatively, also returning output to the Mathematica session:
ReadList["!type c:\\temp\\test.txt", String]
I landed here wanting to run abaqus command line on windows.
The solutions provided here worked out for me (Windows 7, Mathematica 9):
SetDirectory#path;
Run["start /min abaqus job=" <> fileName <> " interactive ask_delete=OFF >> log.txt"]
(Here the abaqus option ask_delete=OFF overwrites an existing simulation results and the >> redirects all the output to a file)
I think, minimizing the window did not run in your case since the executable throws open that window. In that case, this might be of some help
I am trying to run a Matlab script from Windows command prompt but I can't execute it sometimes. The script runs fine when manually launched. Matlab version is 2011a and Windows is Server 2003 SP2. Details:
Script mytask.m is located inside say E:\Production\Project. This is SAVED on Matlab's path.
When I place mytask.m inside bin folder, it executes fine by the command:
`C:\Program Files\MATLAB\R2011a\bin>matlab -r mytask`
If you delete it and try to access it at its original location, the script doesn't run although Matlab editor window is launched:
`C:\Program Files\MATLAB\R2011a\bin>matlab -r "E:\Production\Project\mytask"
Any suggestions please? Thanks.
The syntax for matlab -r is
matlab -r "statement"
In other words, you need to provide some executable commands as the statement. For example:
matlab -r "run E:\Production\Project\mytask"
However, it seems that matlab does not load the customized paths in this way. If you have some customized paths, you probably have to define them in startup.m and place this startup.m in the directory where you invoke matlab.
I didn't check myself, but if you define E:\Production\Project\ as the path in startup.m, you probably can run matlab -r mytask without problem, as mytask will be recognized as a user function/script.
A simple example of startup.m
path(path, 'E:\Production\Project\');
