differnce between fgetl and fgets

definition for fgets

tline = fgets(fileID) reads the next line of the specified file, including the newline characters.

definition for fgetl

tline = fgetl(fileID) returns the next line of the specified file, removing the newline characters.

I tried both on a file with \n but got the same resultat

>> fid=fopen('sweden.se', 'r')

fid =

     5

>> while ~feof(fid) fgetl(fid) end

ans =

var sommer

ans =

 host vinter2 3

ans =

 5 6

ans =

 4 7

>> fclose(fid)

ans =

     0

>> fid=fopen('sweden.se', 'r')

fid =

     5

>> while ~feof(fid) fgets(fid) end

ans =

var sommer

ans =

 host vinter2 3

ans =

 5 6

ans =

 4 7

>>

the file sweden.se is exactly as both read it:

var sommer

 host vinter2 3

 5 6

 4 7

The results are very similiar. Using your method the difference is hard to see, because the line break appears at the end of the line as line break directly followed by a line break.

Better check this by a numerical display of the ASCII values:

fid = fopen('sweden.se', 'r')
while ~feof(fid)
  s = fgetl(fid);
  % disp(s);
  disp(double(s));
end
fclose(fid);

fid = fopen('sweden.se', 'r')
while ~feof(fid)
  s = fgets(fid);
  % disp(s);
  disp(double(s));
end
fclsoe(fid);

You can read the source of the file fgetl.m to see, what happens.
