fgets write -1.000000e+00 in output file

Hello,
I have a code that first opens a file (using fopen), then gets everyline from the file, however, when encountering the end-of-file, and the value is -1, it prints this value in the file generated. Thus, when comparing the original file with the one generated, I have the value -1.000000e+00 written at the end. I want to exclude this value, any suggestions?
file=fopen('poem.txt');
line_ex=fgets(file);
getit{1}=filepath %filepath was indicated before
getit{end+1}=line_ex
while ischar(line_ex)
line_ex=fgets{file};
getit{end+1}=line_ex
end
fclose(file);

It works for me:
fid = fopen('old.txt','rt');
fnd = fopen('new.txt','wt');
while ~feof(fid)
str = fgetl(fid);
fprintf(fnd,'%s\n',str);
end
fclose(fid);
fclose(fnd);
type new.txt
Clearly you are doing something different. But because you do not show your code, I cannot debug it.
