This is what I type and the output I get:

$ cat helloworld.txt



Hello World!

I'm Kanladaporn Sirithatthamrong

6480952

But this is what I want an output to be:

Hello World!



I'm Kanladaporn Sirithatthamrong



6480952

What should I do?
Any suggestions please?

Use pr:

$ pr -Td helloworld.txt

Hello World!

From man pr:

   -d, --double-space

          double space the output



   -T, --omit-pagination

              omit page headers and trailers, eliminate any pagination by form feeds set in input files
