[SOLVED]Global variable in SH script

Question

Hi.
The real code is:
TOTAL_UPG=0
TOTAL_INS=0
TOTAL_DEL=0
STRING_UPG=`echo $1|sed -e 's/\[/\\\[/g;s/\]/\\\]/g'`
LINEA_UPG=`grep -n "$STRING_UPG" $PACMANLOG|awk -F: '{print $1}'`
tail -n `expr $NUM_LINES_PACLOG - $LINEA_UPG 2>/dev/null` $PACMANLOG 2>/dev/null| while read -r linea
do
echo $linea|grep -i "starting full system" >/dev/null
if [ $? -eq 0 ]
then
echo "$TOTAL_UPG $TOTAL_INS $TOTAL_DEL"
break
fi
echo $linea|grep -i "upgraded" >/dev/null
if [ $? -eq 0 ]
then
TOTAL_UPG=`expr $TOTAL_UPG + 1 `
else
echo $linea|grep -i "installed" >/dev/null
if [ $? -eq 0 ]
then
TOTAL_INS=`expr $TOTAL_INS + 1 `
else
echo $linea|grep -i "removed" >/dev/null
if [ $? -eq 0 ]
then
TOTAL_DEL=`expr $TOTAL_DEL + 1 `
fi
fi
fi
done
echo "$TOTAL_UPG $TOTAL_INS $TOTAL_DEL"
I'm trying to parse the pacman.log
When I exec this the exit is 0 0 0, but the lastest value of $TOTAL_UPG was 7.
Edit: Bad example for my problem

Thanks for the fast reply, but was a misspelling, the condition was -ne.
