How to script ftp file transfer from Linux to Linux server

Debbie Fleith — Wed, 26 Jul 2006 15:54:20 GMT

I need to automate the transfer of a bunch of files from one directory from a Linux server to another Linux server.

I'm familair with initiating an automated ftp script from an NT server platform, i.e. "ftp -i -s:path/script_name" and I know what's required in the script.

However, how would I initiate an automated ftp session from Linux?

Is there a better way to automate the transfer of files from Linux to Linux?

I'm just looking for a short-term simple solution here.

To copy files from server to server in Linux you have several options:

Use rsync.
Use scp.
Use ftp.

Read the following documents and choose your preferred method:

I was able to find other automated ftp forum topics on the HP-UX side and have come up with this solution that worked fine:

ftp -n << ENDFTP
user
prompt
ascii
lcd
cd
mget *
ENDFTP

Even you have already solved your problem, I suggest taking a look at lftp (http://lftp.yar.ru/ ). It's the best CLI ftp client I have seen in 15 years. You can script it using via external files, schedule it, pipe files to other applications, apply bandwidth limits and a lot more.

A short tutorial is available at http://www2.papamike.ca:8082/tutorials/pub/lftp.html

Hi Debbie,

You can configure "SSH" first of all.

Then, the best way to automate this task is by writing a "SCRIPT" and schedule its execution using the "CRON" facility.

Whatever Manuel has specified, you can do the same thing while using the "scp" command, all you need to do is to go through its "man" page.

If this is a regular, scheduled FTP, with information that may or may not change, I'd recommend rsync instead of FTP, as you'll only copy bytes that have changed.

If it's new data every time you initiate the FTP, it doesn't much matter which method you choose.

(although rsync can use ssh as a transport, which is much more secure)

Lastly, see if you can modify your ftp script to use sftp instead...

u may use secured ftp(sftp)
$sftp userid@hostname
u will asked for passwd
after that
use following commands ..
*********************************
(1)inorder to get a file from ur account to ur local system use "mget" as follows
mget [filename]
or
get [filename]
(2)inorder to put file from ur local system to ur account use "mput" as follows
mput [filename]
or
put [filename]
**************************************
some other cmds that r useful is
***************************************
cd //Change the directory on the remote computer
chmod //Change the permissions of files on the remote computer
chown //Change the owner of files on the remote computer
dir (or ls) // List the files in the current directory on the remote computer
help (or ?) //Get help on the use of SFTP commands
lcd //Change the directory on the local computer
lls //See a list of the files in the current directory on the local computer
lmkdir //Create a directory on the local computer
ln (or symlink)//Create a symbolic link for a file on the remote computer
lpwd //Show the current directory (present working directory) on the local computer
lumask //Change the local umask value
mkdir //Create a directory on the remote computer
pwd //Show the current directory (present working directory) on the remote computer
rename //Rename a file on the remote host
rm //Delete files from the remote computer
rmdir //Remove a directory on the remote host (the directory usually has to be empty)
version //Display the SFTP version
! //In Unix, exit to the shell prompt, where you can enter commands. Enter exit to get back to SFTP. If you follow ! with a command (e.g., !pwd), SFTP will execute the command without dropping you to the Unix prompt

Take your pick on the solutions mentioned above. I had a similar issue to resolve a while back. I had a short window and a great deal of data to move. I started out using scp. Scp was to slow it was taking hours to move the data. I tried sftp and found it to be even slower that scp. I have found rsync to be faster in almost every case.

If speed is an issue, I would use rsync.
