Hi again!

I have made some modifications to my script, and it displays fairly OK, but I have some issues with the first value soemtimes being a longer string then other value's. Then my display is messed up.

Code looks like this:

Code:
#!/bin/sh
# Usage: script [IP] [user] [filename]

ARGS=3

if [ $# -ne $ARGS ]
then
    echo "$0:Error, missing or too many arguments!"
    echo "Usage: $0 IP user filename"
    exit 1
fi

IPADRESS=$1
USERNAME=$2
FILENAME=$3

get_data()
{
    ssh $USERNAME@$IPADRESS "cat $FILENAME" | awk 'BEGIN{ FS=OFS="," } { print $2"\t\t"$4"\t"$9"\t"$11 }'
}

while true
do
    clear
    echo "Last updated: \c"; date --utc
    echo "Value2\Value4\Value9\t\t\Value11"
    echo "-----------------------------------------------------------------"
    get_data
    sleep 600
done

This is just to make it look more pretty (I guess the inf loop is not optimal either). The data is retrieved well as is, but handy to be able to get an easy overview of the data by displaying it properly.

I have used tabulators to get the desired positions, and this works fine execpt on the occations were the lengt of Value2 is different (the other values do not change as much, value4 might be 2 or 3 in lenght, value9 and value11 is the same all the time). So my question is what canI do to make sure the values are dispalyed propely? E.g. I want to have something that looks like this for all lenghts of values:
Code:
Desription             Desription              Desription            Desription
Value2                 Value4                  Value9                Value11
Value2                 Value4                  Value9                Value11
Value2                 Value4                  Value9                Value11

Use printf in awk. like below
Code:
printf "%-20s\t%-10s\t%-10s\t%-10s\n",$2,$4,$9,$11
