I just want to transfer a file from ftp server to unix folder, --this is stright forward.
if the file doesn't exist on the ftp server, then the script needs to run recursively until it finds the file. Please let me know how do i get that file.
please remember script has to run on ftp server.
Thanks
CK
I'd mount the FTP server with curlftpfs http://curlftpfs.sourceforge.net and then use it like it were a local file system — for example, run find(1).
You need to write a program to automate your FTP session. You can either write your own custom FTP client, not that hard if you know a few things about network programming, or write a script to automate a session for an existing client. For the latter approach, I suggest using Expect if you are proficient with TCL, or PyExpect if you prefer Python. Expect is a library designed to automate interactive tasks like downloading a file with FTP.

I have a file on my desktop and I need to get it onto another server, but I have no means of getting it there, i.e. email/usb or any way like that.
The server is on the same network as me.
I have heard of a way that the file can be copied via the command line.
Would anyone have any information on this and if so could you please help me?
Not sure whether you have command line access to that server or not? If yes, are you accessing it via telnet or via ssh?
If ssh, you should be able to transfer the file via SCP (secure copy), since it uses the same ssh connection you use to get your cli. If you want to transfer your file from a Windows environment, you may want to look at WinSCP, else do a man scp on your Linux or Unix server and, assuming you have it, you'll get the hang of it... it's not complicated.
If ssh is not an option, then you depend on the server having some service available for you to transfer the file, most obvious one being FTP.
Does that help?
Suppose I have a file called helloworld.txt on an AS400 and I want to write a script to automate the daily upload of the source file helloworld.txt on an AS400 server to upload to a Unix SFTP server, say sftp://exampleunixsftp.com?
Does someone have such a script? Is OpenSSH the only tool that can be used on the AS400 to get this accomplished or are there any other methods? If LFTP could be installed on the AS400, that would be an easy solution but since it's only for Unix/Linux/Win/Mac then I don't have this option. I read Scott Klement's article at:
http://systeminetwork.com/article/ssh-scp-and-sftp-tools-openssh
I just need an example basic script to get this done. I'd appreciate this.
The MidrangeWiki topic on SSH has some information and examples that may be helpful.
sftp is intended primarily as an interactive utility. scp performs the same function non-interactively.
The command, once authentication is set up, would simply be:
scp helloworld.txt username#exampleunixsftp.com:<destination path>
LFTP can be installed with some preparation in the PASE environment. See Open Source Binaries. Currently offline. Use the Google cache.
I have a weird problem. I'm using pscp.exe from within a C# program (with process.start) to upload files to an SFTP server. Now I have set up a new server with the same program, where I upload to the same SFTP server as before, but It runs incredibly slow in the new server.
The weird thing is that when I try uploading the files manually via FileZilla, the upload goes as fast as expected, but not when using the program.
Can anyone explain this? Am I missing something obvious like a windows setting or something?
SSH supports what we call pipelining - sending multiple SSH packets without waiting response to each packet. OpenSSH supports this functionality, while Putty doesn't (at least didn't until recently). That's what you observe. Another reason is choice of algorithms. If AES is negotiated, it's faster than DES and 3DES used by default by older applications.
I ended up rewriting the SFTP transfer to use the .Net wrapper for WinSCP in stead. The solution was fast, and the file transfer also. Here's a link to the documentation.
Uploading files using WinSCP is like 10 times faster.
To do that from command line, first you got to add the winscp.com file to your %PATH%. It's not a top-level domain, but an executable .com file, which is located in your WinSCP installation directory.
Then just issue a simple command and your file will be uploaded much faster putty ever could:
WinSCP.com /command "open sftp://username:password#example.com:22" "put your_large_file.zip /var/www/somedirectory/" "exit"
And make sure your check the synchronize folders feature, which is basically what rsync does, so you won't ever want to use pscp.exe again.
WinSCP.com /command "help synchronize"
Filezilla can use multiple concurrent connections and reuse open connections. I believe PSCP is a relatively simple application.
A library like SFTP.NET will probably yield better results than running a child pscp process.
It would also help to use the ZipPackage to compress the files when sending them.
i need to write a script to automate file transfer from one server to another using only sftp .Can you guys provide me some example sftp automated script ??? or some code that would help me !!!
Check out this SO post for some suggestions. Additional details for your server environment would be helpful (LINUX, Windows, etc.).
I'm looking for a way to upload files/dirs structure from one server to another..
The only way it's possible in my case is SFTP upload, is there any easy way to upload it, using script or something without making archive of files/dirs, I want to recreate on remote server?
Thank you!
Perhaps a solution could be found using recursive scp (scp -r)? Or are you limited explicitly to sftp only?
There's also a client named lftp which has sftp and scripting support - much like batch file I would imagine - a list of ftp commands. (http://lftp.yar.ru/lftp-man.html)
You may want to consider Syncplify.me FTP Script! as a solution. It allows you to write very simple scripts to achieve your goal.
For example, uploading an entire directory to a remote SFTP server would actually be a single line of code added to one of the ready-made templates.

edtFTPj/PRO is a Java SFTP client that has a comprehensive scripting engine. Being Java you can run it on any platform where Java is supported.
Here's some more details on the scripting support. It has an 'mput' command that uploads all the files in the current directory to the remote directory.
Recursive transfers aren't yet supported, but could easily be added if required - email support if you are interested.
