"Iam using this part of script in a shell script...
The Tee wont work bcos Iam not just doing ftp."
Well you lost me there... Smilie

"I want the output to be on screen and to a logfile."
I understand that. It's gonna be a bit rough...
Code:
#! /usr/bin/ksh

#
# get password

print -n password -
stty -echo
read PASSWD
stty echo
echo

HOST=someftphost
USER=joeuser

#
# arrange for all stdout and stderr to be sent to a tee process
exec 5>&1
tee /dev/tty > ftptest.log |&
pid1=$!
exec  >&p 2>&1 4>&1

#
# invoke ftp co-process
ftp -nv >&4 2>&4 |&
pid2=$!
print -p open $HOST
print -p user $USER $PASSWD
print -p get foo
print -p bye
wait $pid2

#
# disconnect stdout and stderr from tee process
# send a line to stdout which comes directly from this script
exec >&- 2>&- 4>&- >&5 2>&1
echo
exit 0

Hello Perderabo,

I'd like to ask for further assitance in this regards, If you dont mind.

I have a similar requirement where in I have :-

a) Predefined the desitnation server / hardcoded value.
b) Ask for the TAR file to transfer to the destination server.
c) After the file has been transfered it has to be extracted.

How can i do this and the important question is, how will the extraction and other validations take place via FTP ?

Kindly assist.

Thanks

what about security

Perderabo Thanksa lot for the script example , in the script
HOST=damien1
USER=con
PASSWD=
is there a way to mask this password . The reason being that i do the transfer as myself which in this case I have to expose my password, is there a way to encrypt this.
Thanks for your help guys.

These examples are great and sort of do what I want.
Since I'm not a great scriptor can one of you please help me out.

This is what I have.

- System A is a Solaris server
- System B is a Windows server
- Both systems have an outbound and an inbound ftp dir
- I need to move the lastest file from SystemA outbound to System B inbound dir and also from System B outbound to System A inbound
- The script will be run out of cron on System A
- Both these servers will have files in both the outbound and inbound dir. The script needs to only transfer any new files

I have been told I must use ftp and not rsync as rsync is not allowed through the firewalls but ftp is.

Using the info gathered from this thread, this is what I have so far..
Code:
#! /usr/bin/ksh
#
# Goran Cvetanoski - 07/11/2006
#
# /export/ftpdir/autoftp
#
# This script uses ftp to move files from one server to another.
# It copies files from one servers Outgoing to another servers Incoming
# It FTPs to Incoming/.receiving directory and then moves the files to Incoming
# Once the files have been sent it moves the files from Outgoing to Outgoing/.sent
# It deletes files older then 14 days from both servers Outgoing/.sent directories
# It traps any FTP errors and send an email with the error message
# It can also send emails on successfull transfers, if wanted
#
# Available flags:
# -------------------------------------------------------------------------
# mget - ftp mget from $RHOST:\$ROUT to $LIN
# mput - ftp mput from $LOUT to $RHOST:\$RIN
# xfer - Perform a mget then an mput on $RHOST
#
# Two log files are created:
# -------------------------------------------------------------------------
# ftp.mail - This gets emailed to $ADMIN , if comment removed
# ftp.log  - Verbose output from the ftp
#
# -------------------------------------------------------------------------
#                  A small note on all the fd stuff..
# -------------------------------------------------------------------------
# exec 4>&1
# ftp -nv >&4 2>&1 |&
#
# fd 0 is standard-in, fd 1 is standard-out, and fd 2 is standard-error.
# The line "exec 4&>1" opens fd 4 and assigns it to whatever fd 1 was
# assigned to. I am sorta "saving a copy of fd 1 in fd 4".
#
# The line "ftp -nv >&4 2>&1 |&" is a little harder.
#
# The "|&" turns the process into a co-process that allows subsequent
# "print -p" statements to send lines to the co-process' standard-in and
# "read -p" to read from its standard-out. So ksh forks a copy of itself
# and fiddles with the fd's 0 and 1 until this it set-up. But it leaves
# the rest of the fd's alone.
#
# Then it encounters ">&4" which causes it to set the ftp process' standard
# out to whatever 4 is. Well since 4 is a copy of 1 before the co-process,
# we are back to writing to the original shell's standard out. Lastly,
# the 2>&1 does the same thing for standard error.

This is writen for a Solaris 8 system, thats why I have to do the ls -s and awk stuff and can't just use ls -h in my log function. I also need to remove all files older then 14 days from the .sent directory. This is easy on the server as I just use find, but its a bit more tricky on the remote Windows NT system.

UPDATED
I have updated the code above to include my cleanup function..

I haven't read the entire thread, but when it comes to automated FTP transfers ( every day to backup machine ) use rsync.
