Hi all,
Please tell me to solve this issue,

ROTATE_FILES=" <PATH>"
REAL_FILE="MQ.log"

function rotate_files()
{
for j in $1;do
echo "Loop1"

if [ -d $j ]
then
for i in `ls -a /$j`
do

if [ $i = MQ.log ]
then
echo $i

FILESIZE=`ls -l $i|awk '{print $5}'` #......error......#
LIMIT=0

if [ $FILESIZE -ge 0 ] #......error......#
then
echo "the size is greater"
fi

fi

done
fi
done
}

rotate_files "$ROTATE_FILES"

-----------------------------------------------------------------

FILESIZE=`ls -l $i|awk '{print $5}'`
"ls: MQ.log: No such file or directory" <<<error message

if [ $FILESIZE -ge 0 ]
"[: -ge: unary operator expected" <<<error message

please tell me how to solve this

In case the script is executed from the different directory,then "$i" will expand to MQ.log and not the full path to it,so it throws an error.Either you can try running the script from the directory (ROTATE_PATH) or give the full path

Thanks

change -ge to -gt

check if [[ ! -f $i ]];then
only check the size.
