Script for adding

[Henry Chua]

Hi guys,

I have tried out this in my shell script, doesnt seem to be correct though.. any suggestion?

while(TRUE)
y=0
x=`awk '{ print $5 }' $BUF`
let y=y+x
done

it gave an error "y=y+: more tokens expected"

May I know how this can be corrected?

Try:

integer y=0
while(TRUE)
x=`awk '{ print $5 }' $BUF`
y=$y+$x
done

Hi there.
Here an idea :

export NC0="0"
export NC1="0"
export NC2="0"
export NC3="0"

NC0=`expr $NC0 + 1`
#
#
if [ "$F1" = "72" ]
then
NC1=`expr $NC1 + 1`
elif
[ "$F1" = "76" ]
then
NC2=`expr $NC2 + 1`
elif
[ "$F1" = "78" ]
then
NC3=`expr $NC3 + 1`
fi
#

Hi guys

I used Tripathy suggestion, but I have to initialise as well..

integer x=0
integer y=0
while(TRUE)
x=`awk '{ print $5 }' $BUF`
y=$y+$x
done

It work fine!!

ThankS !!!!
