I am getting the unix command out put and sending into a file, but it is putting all the info in one line.

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

What am I doing wrong?

the command you have there would write the literal string to the $LOG file.  I think you need to remove the "echo" from the command

Omit echo or use quotes:

/sbin/lltstat -nvv active >> $LOG

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

Just for clarification, are you trying to write the output of the lltstat command to a file?  $LOG is a variable, has it been defined?  echo '/sbin/lltstat -nvv active' will literally output "/sbin/lltstat -nvv active" to your $LOG file.

@Trenton - please look a bit closer.  The asker uses backticks, not single quotes.
That's what we call "command substitution".

$LOG is a variable, has it been defined?

if it wasn't defined, bash would have returned an ambiguous redirect

It looks like a line from shell script, not a BASIC script.

How the output of

/sbin/lltstat -nvv active | wc -l

looks like? Is it single line?
