How to automate an FTP session through shell script.

The ftp site name, user name, password has to be user defined during run time, not to be given in shell script.

Can anyone tell me how to do this in shell script.

#Try this ----


echo "Enter ftp user name"
read FTPUSER
echo "Enter ftp user password"
read FTPPASS
echo "Enter destination server"
read FTPSERVER
echo "Enter file to transfer"
read FTPFILE
ftp -n $FTPSERVER <<END_SCRIPT
user $FTPUSER $FTPPASS
put $FTPFILE
quit
END_SCRIPT
exit 0

I thought of removing the line
exit 0
before posting it here but forgot. ( Remove the line if you don't want to exit out of your user session after running the script )

Hi,

It is working fine.

I need some more clarification.

I want to connect to a ftp server and on the ftp server i want to check for the availability of a file.

How to do this in a shell script.

As per your help I am able to connect to the ftp site by getting user password & server details from user. Can I also mention the file to search in the ftp server along with these during run time.

I tried, but it is not working. Can you pls help me

Hi, try this

FTP_USER="guest"
FTP_PASS="guest"
REMOTE_SERV="cd000000"
REMOTE_PATH="/usr/guest/bin"
REMOTE_SEARCH_FILE="Hello.txt"
REMOTE_CMD="ls "$MY_FILE
LOCAL_LOG_FILE="/tmp/MY_FTP_SCRIPT.LOG"
> $LOCAL_LOG_FILE

#start ftp
ftp -n $REMOTE_SERV <<-! 2>&1 | tee -i -a $LOCAL_LOG_FILE | grep -i $REMOTE_SEARCH_FILE > /dev/null 2>&1
user $FTP_USER $FTP_PASS
cd $REMOTE_PATH
$REMOTE_CMD
bye
!

GREP_RESULT="$?"

if [ "$GREP_RESULT" = "0" ]
then
echo "file "$REMOTE_SEARCH_FILE" found"
else
echo "file "$REMOTE_SEARCH_FILE" not found"
fi

Hi,

The file search code is not giving any error, the shell script is working fine during run time.

But the problem is what ever file name i give for search, it is saying file found.

I am not getting the code. Can you kindly explain me.

First :
there is a little bug in my code.

change REMOTE_CMD="ls "$MY_FILE
to REMOTE_CMD="ls "$REMOTE_SEARCH_FILE

Second:
If the script does not still work, look at the LOCAL_LOG_FILE and give
me a hardcopy of it in case the file surely exist and one when the file surely not exist. May be we do it by another way.

Hi,

The shell script is not giving the correct output, even the file is not exist it is giving file found. in the local log file in the very first line it is saying ?invalid command and then the listing of the files in the ftp server.

Can you pls help me, what went wrong.
