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

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
