If you want to avoid the penalty of calling an external utility such as sed, you can do what you want to do entirely within your shell.
Code:
#!/bin/ksh93

n=0
output=""

while read line
do
   output="$output$line"
   if (( n%2 == 0 )); then
      output="$output="
   else
      output="$output "
   fi
   (( n++ ))
   if (( n == 6 )); then
     echo "$output"
     output=""
     n=0
   fi
done < file

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
