MATLAB: Formatting .txt files as the one produced by command prompt.

MATLABtext file

Hi, I have the following script that requests all processes running currently on my machine.

[~,tasks] = system('tasklist');
fileID = fopen('another_test.txt','w');
fprintf(fileID,'%s',tasks);
fclose(fileID);

The file looks like this:

If I try the same thing on the Windows Command Prompt, using this command:

tasklist.exe > %USERPROFILE%\Desktop\processlog.txt

Which gets me this in a nice format which I can't replicate using Matlab. And I would like to get it in the same way, or somewhat similar at least.

The use of delimiters perhaps could help? Any guidance would be great, thanks in advance.

Open the file in text mode:

fileID = fopen('another_test.txt','wt');
%                                   ^ you need this!

and use a proper text editor, e.g. Notepad++.

MATLAB: How to change a specific line in a text file

Loading txt into a cell.
Then do whatever you want with the cell. In this example, line 69 will be 99.
Then write the cell into a txt.

% Read txt into cell A
fid = fopen('test.txt','r');
i = 1;
tline = fgetl(fid);
A{i} = tline;
while ischar(tline)
    i = i+1;
    tline = fgetl(fid);
    A{i} = tline;
end
fclose(fid);
% Change cell A
A{69} = sprintf('%d',99);
% Write cell A into txt
fid = fopen('test2.txt', 'w');
for i = 1:numel(A)
    if A{i+1} == -1
        fprintf(fid,'%s', A{i});
        break
    else
        fprintf(fid,'%s\n', A{i});
    end
end

MATLAB: How to create a list of the processes that are currently running on the system

This article will show you how to run a command that will create a list which represents a snapshot of the processes that are running on your system, and then send the output to a file on your system. The command will create the file for you, you will not need to create it ahead of time. For all of the commands below, you can choose a different location and file name by editing file path and file name in the command.

Windows:

Open the Command Prompt. If needed, use the Search feature in Windows to find the Command Prompt.

Run the following command exactly as it is shown below:

tasklist.exe > %USERPROFILE%\Desktop\processlog.txt

This will create a text document on the desktop called processlog.txt.

Mac:

Open Terminal. If needed, use the Search feature in OS X to find Terminal.

Run the following command:

   ps aux > ~/Desktop/processlog.txt

This will create a text document on your desktop called processlog.txt.

Linux:

Open the Console.

Run the following command:

   ps aux > ~/processlog.txt

This will create a text document in your Home folder called processlog.txt.

Note: If you receive a permissions denied error, make sure that you have listed a file location where you have write permissions. You can also start the Command Prompt on Windows as an Administrator, and run the Mac and Linux commands as sudo in order to override permissions on your target folder.
