About Ftp script
One of the most useful features of Robo-FTP is the ability run a script that transfers files unattended at scheduled times. There are three basic approaches to achieve this result.Option 1: Launching a Robo-FTP Script using the Scheduler.Robo-FTP Includes a built in scheduler. The scheduler configuration and control can be accessed from The Configurator by selecting the Scheduler on the left. Option 2: Launching Robo-FTP as a Windows ServiceInstead of scheduling a script, you may wish to run Robo-FTP as a Windows service so it will be automatically launched whenever the system reboots. Installing Robo-FTP as a Windows service is easy using a service script designed to run in an infinite loop and either the Service Installer or Enterprise Dashboard utilities.Option 3: The Scheduling Script Commands.Regardless of how you launch Robo-FTP, scheduling operations within a command script may be accomplished by using the PAUSE or CRON script commands.The PAUSE command is easy to use and is best suited for simple schedules. This command suspends script execution either for a fixed period of time (e.g., 60 minutes) or until a fixed time of day (e.g., 11PM). At the designated time, the script “wakes up” and continues execution. When this command is used in a service script, it is typically at the top of an infinite loop such that execution waits for the appropriate time then continues to log in, transfer files, and log off before ultimately looping back to the PAUSE command at the top of the loop where it waits for the next designated time to run. The CRON command may be used to create complex schedules. This command, like the PAUSE command, suspends script execution for a period of time and is typically used at the top of a loop. However, unlike PAUSE, the duration of the CRON command's
Key features of the Ftp script that are enabled through these drivers include:

A user ID and password. No use of/dev/tty.Use the ftp client program command quote to senduser ID and password to the ftp server.You must the token that ends the "here document" (END_SCRIPT inthe example above) at the beginning of a line. Even if the ftpcommand line and the login and transfer script are indented, END_SCRIPTshould appear with the 'E' as the first character of the line.Further RefinementsThe above sh script will spew lots of ftp client outputto standard output. Even if everything works perfectly, the userrunning the above script will see lots of incomprehensible textscrolling by quite rapidly. One refinement would send output todifferent places: ftp -n $HOST > /tmp/ftp.worked 2> /tmp/ftp.failed One could further refine error handling by acting on the ftp clientprogram's exit status: ftp -n $HOST > /tmp/ftp.worked 2> /tmp/ftp.failed blah blahEND_SCRIPTEXITSTATUS=$?if [ $EXITSTATUS != "0" ]then # handle the error...fi Except that the above doesn't always work - most FTP clients alwaysexit with a status of 0. This leads to ugly "false negatives": the filetransfer fails, but the script doesn't detect the problem.One way to verify that a file transfertook place - transfer it back:#!/bin/shftp -n Regular FTPs there and back of large files can consume a lot of time.Control of ftp by a shell scriptOne obvious improvement would have the ftp client programcontrolled by the shell script. I don't think that would comprisean impossible task, but I also don't think that it would have muchvalue. Scripting ftp transfer using expect might cause you less pain.Alternative
