ftruncate

  • We use the ftruncate function in PHP to truncate a file to a given length.

    PHP

    $f = fopen('/path/to/foobar', 'w')
ftruncate($f, 10);
fclose($f);

    The same task can be accomplished in Ruby with the File#truncate method:

    Ruby

    File.open('/path/to/foobar', 'w') do |f|
  f.truncate(10)
end

    Ruby also provides the File.truncate class method for convenience. It allows you to truncate a file without opening it yourself.

    Ruby

    File.truncate('/path/to/foobar', 10)
