simple script not working

[teakandme]

I created the following script, which is simple by nature, but can not get it to run properly. I exported each variable and echo the varible at the command line to confirm that the variable is returning value, but this will not write out/append to the file as intended. I think I am missing something?

#!/usr/bin/ksh #
# #
# Script: lth_test #
# #
# Rev By Date Description #
# 1.0 Lien Huynh 05/18/2006 This will append to a file that will #
# maintain the minimum avaiable and the date/time #
# so trending and/or analysis can be done later #

DATE1='date'
FILE1="/home/lhuynh/lth_test.dat"

#The following command gets the numerical value of the minimum available

MIN_VAL='grep -E "minimum available" /cachesys/mgr/ckey.out|tr -s '[:space:]'|cut -d" " -f5'

echo "$MIN_VAL $DATE1" >> $FILE1

#grep -E "minimum available" /cachesys/mgr/ckey.out|tr -s '[:space:]'|cut -d" " -f5 >> lth_test.dat

 

[PHV]

DATE1=$(date)
FILE1='/home/lhuynh/lth_test.dat'
MIN_VAL=$(grep -E "minimum available" /cachesys/mgr/ckey.out|tr -s '[:space:]'|cut -d" " -f5)
echo "$MIN_VAL $DATE1" >> $FILE1

Hope This Helps, PH.
