how to read all line except the first line? is there a way to read only 2nd up to the last line except for the first line?

here's my sample code

File myFile;
char cr;
void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }


  Serial.print("Initializing SD card...");

  if (!SD.begin(4)) {
    Serial.println("initialization failed!");
    while (1);
  }
  Serial.println("initialization done.");



  // re-open the file for reading:
  myFile = SD.open("test.txt");
  if (myFile) {
    Serial.println("test.txt:");

    // read from the file until there's nothing else in it:
    while (myFile.available()) {
      Serial.write(myFile.read());



    }
    // close the file:
    myFile.close();
  } else {
    // if the file didn't open, print an error:
    Serial.println("error opening test.txt");
  }
}

void loop() {
  // nothing happens after setup
}
Why don't you do reads for the first line, ignore them and start the while thus:

while (myFile.available() &amp;&amp; (myFile.read() != '\n') {}; // Empty while body
while (myFile.available()) {
  Serial.write(myFile.read());
}
