FTP using specific multiple directories

Hi, How can I open the ftp connection 1 time and then get the files from the specified directories from
my control file, put these to my local server in the specified location from the control file
and then close the connection at the end?
my script is opening and closing the connection for each file in the control file and hanging up often.
Thanks!

export TERM=vt100
CurrDate=`date +%Y%m%d%H%M%S`
Logfile=/home/Log.$CurrDate
temp="/home//temp"
controlfile="/home/ftp.ctl"
newline=\\n
filepattern="*"
ipaddress="xxx.xx.xx.xx"
userid="xxxxxxxx"
password="xxxxxxxx"
trap '' 1 2 3 4 5 6 13 15 18 24 29
if ls "$controlfile" > /dev/null
then
for file in `cat $controlfile | cut -d: -f3 `
do
localdir=`cat $controlfile | grep "$file" | cut -d: -f2`
remotedir=`cat $controlfile | grep "$file" | cut -d: -f3`
tempdir=`cat $controlfile | grep "$file" | cut -d: -f1`

cd $localdir
if ping -c 3 $ipaddress > /dev/null
then
{
echo "
open $ipaddress
user $userid $password
cd $remotedir/Pending
ascii
dir *.in listfile
mget *.in
quit
"
} | ftp -i -n

else
clear
rm $temp/filename
rm $file/filelist
exit 8
fi
if ls "$tempdir/listfile" > /dev/null
then

for x in `cat $tempdir/listfile | cut -c 40-100`

do


cd $localdir
ls > filelist1

d=`date`
if ! cat filelist1 | grep "$x" > /dev/null
then
echo "Please check" $x "is missing or cannot be located ">> $Logfile

echo "Got the file " $x >> $Logfile

{

Only had a short glance at your code. I am not into reading that much of code in my free time...

Suggestion: open a named pipe (instead of your unnamed one aka "|") to the ftp server and redesign your loops. then you can supply several commands for one connection.
eg.:

assume this to be some kind of pseudo-code and being untested. i take no responsibility if you delete all your files like this or whatever
