fgets

Reads one line from a file and keeps the newline character.

Category: Data Import and Analysis > Data Import and Export

Syntax

tline = fgets(fid)

Description

fgets is the same as fgetl except that the line terminator stays in the result, so the length of the text tells you whether the last line ended with a newline. This matters when you are copying data byte for byte.

Input arguments

fid

File identifier from fopen.

Output arguments

tline

Character vector with the line, or -1 at the end of the file.

Example

Newline kept

fid = fopen('h.txt', 'w');
fprintf(fid, 'abc\n');
fclose(fid);
fid = fopen('h.txt');
s = fgets(fid);
fclose(fid);
numel(s)
double(s(end))

ans = 4
ans = 10
