Returning null password when read decrypted password from decryppwd.sh file

Question

I am working on Java web application that should get the decrypted password from .sh file. (e.g file name: decryppwd.sh)

My issue is it returns a blank password when using variable inside the decryppwd.sh file.

E.g:
#decrypted password#
pwd='Welcome123'
echo pwd
#returns: ''

But if we directly use echo to return the password; it is returning the password from decryppwd.sh file.

E.g:
#decrypted password#
echo 'Welcome123'
#returns: Welcome123

My code:

public static String callPwdShellScript(String schema) throws IOException {
    String s = null;
    Process p =null;
    String hostname =null;
    String value2 ="oracle";
     

    try {
          p = Runtime.getRuntime().exec(“/usr/bin/bash /app/project/config/decryppwd.sh”);
        
      BufferedInputStream buffer = new BufferedInputStream(p.getInputStream());
             BufferedReader commandResult = new BufferedReader(new InputStreamReader(buffer));
             String line = null;
             
                while((line = commandResult.readLine())!=null)
                    {     
                        value2 = line; 
            }   
  
        catch(IOException e)
         {        
            e.printStackTrace(); 
            logger.error("callPwdShellScript IOException: " + e.getMessage());  
         }
         catch(Exception e) {
             logger.error("callPwdShellScript Exception: " + e.getMessage()); 
         }
        
        return value2;   
}  

Please let me know where I have gone wrong.

I was able to solve my issue by reading only 1st line of the BufferedReader.
