Why should you want to use "echo" with "cat"?

This is sufficient:

cat $PWD/testing >> $LOG

The cause of your issue is that "echo" strips linefeeds (and adds one at the end only).
To avoid this you could do:

echo "`cat $PWD/testing`" >> $LOG
or (better readable):
echo "$(cat $PWD/testing)" >> $LOG

Please note the quotation marks!

But as I said, "echo" is unnecessary.

How about if I want to run a commnad get the output line by line.

 I am trying a command , and it has 5 lines, but I can only use echo command

echo `/sbin/lltstat -nvv active` >> $LOG

Well, I'm not familiar with lltstat. Seems it's used to report LLT statistics, right?

Anyway, what do you mean with "line by line", and why in the world "echo"?

I'm rather sure that this is not what you want:

for line in $(/sbin/lltstat -nvv active)
   do
      echo "This is a line:" $line
      echo "Hit <Enter> for next line"
       read IN
   done

But what else?
