How can I parse multiple entire lines of text into octave 'matrix' - octave

Question

I want to import a lot of data from multiple files from multiple sub files. Luckily the data is consistent in its output:
Subpro1/data apples 1
Subpro1/data oranges 1
Subpro1/data banana 1
then
Subpro2/data apples 1
Subpro2/data oranges 1
Subpro2/data banana 1
I want to have a a datafilename array that holds the file names for each set of data I need to read. Then I can extract and store the data in a more local file, process it and eventually compare 'sub1_apples' to 'sub2_apples'
I have tried
fid = fopen ("DataFileNames.txt");
DataFileNames = fgets (fid)
fclose (fid);
But this only gives me the first line of 7.
DataFileNames = dlmread('DataFileNames.txt') gives me a 7x3 array but only 0 0 1 in each line as it reads the name breaks as delimiters and I cant change the file names.
DataFileNames = textread("DataFileNames.txt", '%s')
has all the correct information but still the delimiters split it across multiple lines
data
apples
1
data
oranges
1
...
Is there a %? that I am missing, if so what is it?
I want the output to be:
data apples 1
data oranges 1
data banana 1
With spaces, underscores and everything included so that I can then use this to access the data file.

You can read all lines of the file to a cell array like this:
str = fileread("DataFileNames.txt");
DataFileNames = regexp(str, '\r\n|\r|\n', 'split');
Output:
DataFileNames =
{
[1,1] = data apples 1
[1,2] = data oranges 1
[1,3] = data banana 1
}
In the first option you tried, using fgets you are reading just one line. Also, its better to use fgetl to remove the line end. To read line by line (which is longer) you need to do:
DataFileNames = {};
fid = fopen ("DataFileNames.txt");
line = fgetl(fid);
while ischar(line)
if ~isempty(line)
DataFileNames = [DataFileNames line];
endif
line = fgetl(fid);
endwhile
fclose (fid);
The second option you tried, using dlmread is not good because it is intended for reading numeric data to a matrix.
The third option you tried with textread, is not so good because it treats all white spaces (spaces, line-ends, ...) equally
