Linux If Condition Issue in UNIX

Hi

I am trying to do a "IF" Condition in UNIX where we compare EACH file size in a directory with a SIZE (Parameter passed)

If Each File size EXCEEDS parameter passed SIZE then we manipulate the file.
Somehow the IF condition do not work ?? (is this Variable decalration issue ??)

Code:
 
APPS_USER_PWD=$1
APPS_USER_ID=$2
APPS_USER_NAME=$3
REQUEST_ID=$4
DIR=$5
FILE_NAME=$6
FILE_SIZE=$7
############
echo "DIRECTORY passed to the Program "$DIR
echo " "
echo "File Name passed to the program "$FILE_NAME
echo " "
echo "File Size passed to the program "$FILE_SIZE
XML_PATH_FLAG=`sqlplus -s $APPS_USER_PWD<<EOF
set head off 
set feedback off 
set echo off 
set term off 
set pages 0
set linesize 9000 
set trims on
select directory_path from dba_directories where directory_name = '${DIR}';
EXIT
EOF`
echo " "
echo "The Path Obtained to pick up Order XML Files is $XML_PATH_FLAG"
echo " "
echo "Permissions changing on XML files "
echo " "
cd $XML_PATH_FLAG
chmod 777 *.xml
echo " "
echo "Permission Changes Completed "
 
# To Loop in the Direcorty path for each file one at a time & modify each file
 if [ "X$FILE_NAME" == "X" ] ; then # Only Directory is passed , File name echo "FILE_NAME parameter not passed ....."
echo $XML_PATH_FLAG*.xml
for file in $XML_PATH_FLAG*.xml
do 
actual_size=`du $file` # getting each file Size 
 
echo " OUTSIDE CONDITION file_size is " $actual_size " and parameter_size echo  " sent is " $FILE_SIZE " for " $file 
 
if [ $actual_size > $FILE_SIZE ] ; then ### we are comapring each file size with PARAMETER passed constant SIZE ###CULPRIT??
##THE ABOVE CONDITION do not work ###
sed -i $file -e 's/<\/ItemOut>/&\n/g;' 
 
fi
done
fi

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.11 30 Jan 2004 script(1)
