Hello there,

I have 500 text files with names R1.txt to R500.txt.

How can delete lines 5002 to 5012 from all the text files and save them in the same text files?

Many thanks.

在 MATLAB Online 中打开

folder = '???'
for iFile = 1:500
  % Create file name:
  File  = fullfile(folder, sprintf('R%d.txt', iFile));
  % Import file and modify the contents:
  DataC = strsplit(fileread(File), '\n');
  DataC(5002:5012) = [];
  % Overwrite the file:
  fid   = fopen(File, 'w');
  if fid == -1
    error('Cannot open file for writing: %s', File);
  end
  fprintf(fid, '%s\n', DataC{:});
  fclose(fid);
end
