For loop in bash - Direct output to two files

Hello all,

i have a code in which when doing a for loop, i need to direct the output to two files, one just a single output, the other to always append (historical reasons).

So far i managed to do the following, which is working, but am still considering it as "dirty".

Code:

INTERFACE_NAME=`$SNMP -v2c -c $COMMUNITY $HOST ifDescr | awk '{print$4}'`
for int in $INTERFACE_NAME
do
inOct1=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)1 | awk '{print$4}' | tr -d "incoming="`
inOct2=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)2 | awk '{print$4}' | tr -d "incoming="`

outOct1=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)1 | awk '{print$5}' | tr -d "outgoing="`
outOct2=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)2 | awk '{print$5}' | tr -d "outgoing="`

speed=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)1 | awk '{print$3}' | tr -d "speed="`
status=`grep "$int " $HOMEDIR/cron/tmp/$(basename $0 .sh)1 | awk '{print$1}' | tr -d "state=" | tr -d "([0-9])"`

#Diff the polls, divided by the interval
if [ $outOct2 -lt 0 ] || [ $outOct1 -lt 0 ] || [ $inOct2 -lt 0 ] || [ $inOct1 -lt 0 ]; then
    echo "Negative numbers not allowed...exiting"
    exit 1
fi

inUsage=`echo $(((inOct2 - inOct1) / TIME_INTERVAL))`
outUsage=`echo $(((outOct2 - outOct1) / TIME_INTERVAL))`

#Convert to bits
inUsage=`echo $((inUsage * 8))`
outUsage=`echo $((outUsage * 8))`

#get usage in percantage
perinUsage=`echo "scale=4;((($inUsage/$speed) * 100))" | bc`
perinUsage=`printf '%.3f\n' $perinUsage`
peroutUsage=`echo $(((outUsage/speed) * 100)) | bc`
peroutUsage=`printf '%.3f\n' $peroutUsage`

echo $DATE "|" $int "|" $speed "|" $status "|" $inUsage "|" $perinUsage "|" $outUsage "|" $peroutUsage
done | tee $OUTPUTDIR/$(basename $0 .sh) | tee -a  $HISTDIR/${DATESTAMP}.$(basename $0 .sh)

#Remove LOCK
rm -f ${LOCKFILE}

As you can see this is the interesting part:

Code:

echo $DATE "|" $int "|" $speed "|" $status "|" $inUsage "|" $perinUsage "|" $outUsage "|" $peroutUsage
done | tee $OUTPUTDIR/$(basename $0 .sh) | tee -a  $HISTDIR/${DATESTAMP}.$(basename $0 .sh)

where i need to output to two files.

Is there a way to simplify this by making the for loop output to two files and making the output to not show in the screen?

Thanks in advance for your comments

__________________________________________________________________________________________________________________________________________________

NAME

       continue - Skip to the next iteration of a loop

SYNOPSIS

       continue
_________________________________________________________________

DESCRIPTION

       This  command  is  typically invoked inside the body of a looping command such as for or foreach or while.  It returns a TCL_CONTINUE code,
       which causes a continue exception to occur.  The exception causes the current script to be aborted out to  the  innermost  containing  loop
       command,  which	then  continues with the next iteration of the loop.  Catch exceptions are also handled in a few other situations, such as
       the catch command and the outermost scripts of procedure bodies.

EXAMPLE

       Print a line for each of the integers from 0 to 10 except 5:
	      for {set x 0} {$x<10} {incr x} {
		 if {$x == 5} {
		    continue
		 }
		 puts "x is $x"
	      }
