Shell Programming and Scripting

All, I'm having 4 .zip files that are coming from FTP. I need to unzip those files and put that files into another folder. Can anyone help me how to write a shell script to check wether .zip files are located in FTP folder, if condition true then how to unzip and put it in another folder. Thanks in advanace.

try this
----------------------
CURRENDIR=/home/anupl/sri

cd $CURRENDIR
rm $CURRENDIR/zipfiles 2>/dev/null

ls -1 *.zip
if [ $? -eq 0 ]
then
echo ".zip file found"
ls -1 $CURRENDIR/*.zip > $CURRENDIR/zipfiles
for i in `cat $CURRENDIR/zipfiles`
do
unzip $i
done
fi
if [ $? -eq 1 ]
then
echo "NOT found"
fi

ls -1 *.zip > filelist
for filename in `cat filelist`
do
unzip $filename > temp
mv temp newdir/$filename
done
