Do you want to do any additional processing while the file is being transferred? If not, I don't see why the transfer process should be separated from the main process.
Otherwise, here's a small script on how to use fork:
Hi,
Thanks for your reply. My sense is that FTP should not be depended on the main process it should be as an background process. Yes there are chances of additional processing while the file is being transferred
Suppose my main program is main.pl and ftp is callftp.pl how do i utilize the above program and put callftp.pl as an background program?
Hello all,
How do I start a background process and save the process id to a file on my system. For example %wait 5 & will execute and print the process id. I can't figure out how to get it to a file. I've tried: > filename 0>filename 1>filename.
Any assistance is most appreciated.
Thanks,

ncftpls
ncftpls(1) General Commands Manual ncftpls(1)NAME
ncftpls - Internet file transfer program for scripts
SYNOPSIS
ncftpls [options] ftp://url.style/host/path/name/
OPTIONS
Command line flags:
-1 Most basic format, one item per line.
-l Long list format.
-R Long list format, recurse subdirectories. Equivalent to "-x -lR".
-x -XX Additional ls flags to pass on to the server.
-u XX Use username XX instead of anonymous.
-p XX Use password XX with the username.
-P XX Use port number XX instead of the default FTP service port (21).
-d XX Use the file XX for debug logging.
-t XX Timeout after XX seconds.
-E Use regular (PORT) data connections.
-F Use passive (PASV) data connections. The default is to use passive, but to fallback to regular if the passive connection fails or
times out.
-r XX Redial a maximum of XX times until connected to the remote FTP server.
-W XX Send raw FTP command XX after logging in.
-X XX Send raw FTP command XX after each file transferred.
-Y XX Send raw FTP command XX before logging out.
The -W, -X, and -Y options are useful for advanced users who need to tweak behavior on some servers. For example, users accessing
mainframes might need to send some special SITE commands to set blocksize and record format information.
For these options, you can use them multiple times each if you need to send multiple commands. For the -X option, you can use the
cookie %s to expand into the name of the file that was transferred.
DESCRIPTION
The purpose of ncftpls is to do remote directory listings using the File Transfer Protocol without entering an interactive shell. This
lets you write shell scripts or other unattended processes that can do FTP.
The default behavior is to print the directory listing in columnized format (i.e. ls -CF), but that is not very useful for scripting. This
example uses the -1 flag, to print one file per line:
$ ncftpls -1 ftp://ftp.ncftp.com/pub/ncftp/
You can also do a remote "ls -l", by using "ncftpls -l". If you want to try other flags, you have to use them with the -x flag. For exam-
ple, if you wanted to do a remote "ls -lrt", you could do this:
$ ncftpls -x "-lrt" ftp://ftp.ncftp.com/pub/ncftp/
By default the program tries to open the remote host and login anonymously, but you can specify a username and password information like
you can with ncftpget or ncftpput.
DIAGNOSTICS
ncftpls returns the following exit values:
0 Success.
1 Could not connect to remote host.
2 Could not connect to remote host - timed out.
3 Transfer failed.
4 Transfer failed - timed out.
5 Directory change failed.
6 Directory change failed - timed out.
7 Malformed URL.
8 Usage error.
9 Error in login configuration file.
10 Library initialization failed.
11 Session initialization failed.
