Question FTP scripting issue

I dont have enough bits to post in emergency, but I have an urgent FTP issue. A client of ours wants us to pull files from his server onto our server at which point we can process it. I ask a friend what to do, but I was just give the things to do, not how to do it.

I havent written a Unix script before, but I need to understand the basic syntax to FTP a file from a remote server. I've tried to read about it online, but there are sooo many different answers.

I just need to do these things:

Set a parameter to control the dates to be pulled (Script will run Monday-Thursday only) Needs a control file to decide how many files to pull.

pull 3 files from 3 servers with it being 1 file per server usually.
rename these files to add "-A","-B" "-C" on the ends
and then push to our servers. We have four servers

My biggest issue is with variables. I don't know how to use them. I need to call an .sh file to set the variables and then save the last successful run parameter. I don't even know what that means.

Help! I'd be very grateful.

Need few clarification here...
you were talking about control file which decides the number of files to be pulled and in next line you are saying pull 3 files from 3 servers? so control file willhave file names to be pulled?
Also when you say renaming the files is it upon pulling it on your server or on host server?

You can control the days/dates when it should run via scheduling it in crontab.

Well the client provides us with one file perday, but we aren't running the script everyday. So the control file needs to tell us how many files are on our clients server that need to be pulled.

Renaming needs to be done upon pulling the from our clients server before pushing it onto our server.

When I say scheduling, I think something like a variable or parameter that says "its monday" so run the script. How do we control that in crontab?

You have to design diff script where client provided filenames can be entered along with the server name/IP address with , or | seperated format (i assumed , here)

Write something like below (Its just basic one can be modified as per your need)
Code:
 
#!/bin/sh
USER='Username'
PASSWD='password'
while read line ; do
FILE=`awk -F"," '{print $2}'`
HOST=`awk -F"," '{print $1}'`
ftp $HOST <<END_SCRIPT
user $USER
$PASSWD
gut $FILE $FILE"_A"
quit
END_SCRIPT
done < control_file.txt


Your crontab entry to run script every Mon-Thur at 9AM (you can change it as per req.)
Code:
 
09 00 * * 1,4 <<path of the script>>

is it possible to go to the server, list the files in a directory and then save those file names as a parm,
then in the next part ftp $FILE1, $FILE2, $FILE3 and rename them?
