OK, let me try again. I appreciate my code thus far mat be sloppy, forgive me, but as I previously stated, this is something I am learning and hoping to improve upon.

This is my code so far:

Code:
#!/bin/bash

# Fixed Variables
TMP=/tmp/tmpx
HEAD="Filesystem Size Used Avail Use% Status"
DATA=$(df -h | gawk '$5 ~ "/data"')
BINLOGS=$(df -h | gawk '$5 ~ "/binlogs"')
BACKUPS=$(df -h | gawk '$5 ~ "/backup*"')


# Get The Filesystem Stats
echo ""
hostname
echo $HEAD | awk '{printf("%-30s\t %s\t %s\t %s\t %s\t %s\t \n", $1, $2, $3, $4, $5, $6)}'
echo $DATA > $TMP
echo $BINLOGS >> $TMP
echo $BACKUPS >> $TMP
cat $TMP | sed 's/%//g' | awk '{printf("%-30s\t %s\t %s\t %s\t %s\t %s\t \n", $5, $1, $2, $3, $4, $6)}'
rm $TMP
exit 0

And it produces this output:

Code:
PACMYDB03
Filesystem                       Size    Used    Avail   Use%    Status
/usr/local/mysql/data            20G     220M    19G     2
/usr/local/mysql/binlogs         15G     52M     14G     1
/usr/local/mysql/backups         25G     44M     24G     1

I want to be able to add a value of "OK" or "Space Required" under the 'Status' colum of each line based on a result of a conditional test of column $4 (something along of the lines of {if ($4 -ge 1){$6="OK"} or {if ($4 -ge 2){$6="Space Required"}.

Am I making sense?

I'm using Red Hat 6

Many Thanks

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
