In Windows, by default the EOL Character is "\r\n". But I have to change the EOL Character as "\n".

How can I convert the string from windows format to UNIX format?

This is the string which I am sending from windows to unix server. 

ASPII90 ASPII90 dsascot 00000066YHDASCDRCD\t0700\t9\tASPII90\tA2185\t1234\n YRQ\t\t\t000415832\n YTRENDDRCD\t3\n

But in server, each \n is converted into whitespace followed by "\".(i.e)

YHDASCDRON>0400>9>ASPII90>A2185>128 \

    (And contrary to your tags, you shouldn't need a regex.) – Jon Skeet Dec 18 '13 at 07:05

  • This question seems unrelated to windows EOL characters. The example input you've provided does **NOT** contain any `\r` characters. Neither does the example output you've provided! – jahroy Dec 18 '13 at 07:29
  • You should provide some details about **how** you're sending strings from windows to a UNIX server... and how you're retrieving them (and printing them) on the server. Are you sending requests to a servlet? Are you using sockets? How are we supposed to guess? – jahroy Dec 18 '13 at 07:32
  • Hi jahroy, If " \n " specified in the string, it will automatically appends the " \r\n ". But i won't be visble. It will happen in back end. please read about the EOL Characters in different operating systems. – Sathesh Subburaj Dec 18 '13 at 07:35
  • I am **very** familiar with the EOL characters used by different operating systems. I have dealt with this issue many times. If you're really having a simple newline issue, the answers below should solve your problem. My guess is your problem is somewhere else. Feel free to ignore me. – jahroy Dec 18 '13 at 07:37
  • Here's [another way](https://code.google.com/p/ec2manager/source/browse/trunk/Ec2+Manager/src/com/unience/util/Dos2Unix.java?spec=svn4&r=4) to do it... – jahroy Dec 18 '13 at 07:46
  • @Jahroy: While i am firing the request from putty, If i created the unix formatted request using notepad++ feature, the server accepts and giving the response. If i use windows format, Its throwing same error as what i have asked in question. – Sathesh Subburaj Dec 18 '13 at 08:32

here is an possible example Code (link to docs: String.replace():

public class HelloWorld{

 public static void main(String []args){
    System.out.println("Hello World");
    String myString ="asdasdasdasdassdasdasd\r\n";
    System.out.println(myString.replace("\r\n","\n"));
 }
}

  • I have tried this. no use. By default, the windows will take the " \r\n " instead of " \n ". Because that is the default EOL Character in windows. – Sathesh Subburaj Dec 18 '13 at 07:18

Use notepad++

Open file in notepad++, select Edit, EOL Conversion, UNIX Format.

Done

You can use BufferedReader's readLine() method to read each line.

readLine()method will remove \r\n for you

Then use BuffereWriter.write() to write this line append with '\n'

  BufferedReader reader = new BufferedReader(new FileReader("xx"));

    BufferedWriter writer = new BufferedWriter(new FileWriter("yy"));

    String line = null;
    while ((line = reader.readLine()) != null) {
        writer.write(line + "\n");
    }

String is immutable, but you can create a new local string to be used as the return value:

String newString = originalStringNameWithManyLineBreaks.replaceAll("\r\n" , "\n");

now only send the value of newString to your server
