How to insert a new line before a character in file?

Hi, I have a file .txt format:

$text-text-text-text-text-text$text-text-text-text-text-text-text$text-text-text-textc....

I want to convert:

$text-text-text-text-text-text

$text-text-text-text-text-text-text

$text-text-text-text

$text-text-text-text

....

And don't have new line at beginning of text.

Thank you

What is the wanted output? A cell string? A string? Another file?

% Perhaps: str = fileread('yourFile.txt');
str = '$text-text-text-text-text-text$text-text-text-text-text-text-text$text-text-text-text';
str = strrep(str, '$', [newline, '$']);
str(1) = [];

And to write this to a file:

writelines(str, 'outFile.txt');

str = '$text-text-text-text-text-text$text-text-text-text-text-text-text$text-text-text-textc' 

str = '$text-text-text-text-text-text$text-text-text-text-text-text-text$text-text-text-textc'

 s = strsplit(str,'$') ;
 s'

ans = 4×1 cell array
    {0×0 char                            }
    {'text-text-text-text-text-text'     }
    {'text-text-text-text-text-text-text'}
    {'text-text-text-textc'              }

Thank you. But how can i edit in a file and keep character "$"

You can read the file into a string using textscan. To each line you can append $.

str = '$text-text-text-text-text-text$text-text-text-text-text-text-text$text-text-text-text' ;
s = strsplit(str,'$')' ;
s(1) = [] ;
for i = 1:length(s)
    s{i} = ['$',s{i}] ;
end
s

s = 3×1 cell array
    {'$text-text-text-text-text-text'     }
    {'$text-text-text-text-text-text-text'}
    {'$text-text-text-text'               }

You can omit the loop:

for i = 1:length(s)
    s{i} = ['$',s{i}] ;
end

using:

s = strcat('$', s)
