Create script.sh and cut paste the following contents

ls *.arc 2> /dev/null
if [ $? -eq 0 ]

gzip $i

One way is to keep the code snippet in while loop with a
sleep time of 300 seconds (expecting 5 minutes time gap)


while true
do
FILE_EXIST_CHECK=`ls -l | grep ^- | wc -l`
if [ $FILE_EXIST_CHECK -ne 0 ];
then
if [ -f *.arc ];
then
ls *.arc > arc_files.lst
while read arc_filename
do
/usr/local/bin/gzip $arc_filename > /dev/null 2>&1
done < arc_files.lst
fi
else
echo " There are no .arc files existing...."
fi
sleep 300;
done

The other way is to schedule the job using crontab with a
time slice of minutes with out keeping in while true loop.
