I understand that the script present in the text file is executed partially when you use the above code block.
The issue you're facing is related to how the ‘stdin.Write(txt)’ function handles newline characters in the text file. By default, ‘fread’ reads the text file as a binary file, which may cause issues when writing to the command prompt.
You could try using 'fgetl' function to read your text file. The following code should work for your case.
% Create a cell array to store the commands
commands = {};
% Replace with path to file with series of commands:
fid = fopen('C:\Users\User\MATLAB\Matlab.txt', 'r');
line = fgetl(fid);
% Read each line from the file
while ischar(line)
commands{end+1} = line;
line = fgetl(fid);
end
fclose(fid);
% Start the command prompt process
Process = System.Diagnostics.Process;
Process.StartInfo.FileName = 'C:\windows\system32\cmd.exe';
Process.StartInfo.UseShellExecute = false;
Process.StartInfo.RedirectStandardInput = true;
Process.StartInfo.CreateNoWindow = false;
Process.Start();
% Write each command to the command prompt
stdin = Process.StandardInput;
for i = 1:numel(commands)
stdin.WriteLine(commands{i});
end
% Wait for cmd.exe to finish processing (option 1)
pause(1); % pause for a predefined amount of time
This updated code reads the text file line by line using 'fgetl' and stores each command in a cell array. Then, it iterates over each command and writes it to the command prompt using ‘stdin.WriteLine’. This approach ensures that newline characters are handled correctly, allowing all commands to be executed properly.
You can refer to the following documents to see the difference between 'fgetl' and 'fread':
