In vi, go into the command mode by keeping the following

If you position your cursor in that line, by typing the "," (comma) key it will delete the current line and paste it below the current cursor. Basically it swaps the two lines.
Thanks for your reply.But sorry i didn't get you properly.Can you put the logic in steps if you don't mind - for swapping two lines in vi editor.

NAME
ed - editor SYNOPSIS
ed file OPTIONS
- Suppress line/byte count messages (for in scripts) EXAMPLES
ed prog.c # Edit prog.c echo '1,$p' | ed - file # Odd way to write 'cat file' DESCRIPTION
Ed is functionally equivalent to the standard V7 editor, ed. It supports the following commands: (.) a: append (.,.)c: change (.,.)d: delete e: edit new file" f: print name of edited file" (1,$)g: global command (.) i: insert (.,.+1)j: join lines together (.) k: mark (.) l: print with special characters in octal (.,.)m: move (.,.)p: print q: quit editor" (.) r: read in new file (.,.)s: substitute (1,$)v: like g, except select lines that do not match (1,$)w: write out edited file Many of the commands can take one or two addresses, as indicated above. The defaults are shown in parentheses. Thus a appends to the cur- rent line, and g works on the whole file as default. The dot refers to the current line. Below is a sample editing session with comments given following the # symbol. ed prog.c # Edit prog.c 3,20p # Print lines 3 through 20 /whole/ # Find next occurence of whole s/whole/while/ # Replace whole by while g/Buf/s//BUF/g # Replace Buf by BUF everywhere w # Write the file back q # Exit the editor Ed is provided for its sentimental value. If you want a line-oriented editor, try ex. If you want a good editor, use elle, elvis, or mined. SEE ALSO
elvis(1), elle(9), mined(9). ED(1)
