how to convert an ftp command to sftp

[Thomas Jones2]

code snippet example:

ftp -i -v pla_img_prod >/app/pro1/if/image_retrieval/image_retrieval_work_out/if280ftp20031021090405.0001.log 2>&1 << !
binary
get "lolc4\LC3034\ky575184001ad65b.pdf" /app/pro1/if/image_retrieval/image_retrieval_work_in/ky575184001ad65b.pdf

So, "man sftp" didn't work?

Is there some particular mystery here, or are
you completely bewildered?

Sometimes you get more help if you appear to
be trying to solve the problem yourself,
rather than asking others to do your whole
job for you.

Just a thought.

Shalom,

You could just use scp, which will work without any scripting.

See this doc:
http://www.hpux.ws/?p=10

safe, secure password free openssh, which includes sftp,ssh and scp.

SEP,

I would prefer to use scp, but we are under mandate to uses sftp.

Unfortunately, according to the man page sftp "is an interactive file transfer program" which is not what we need for batch processing. The [-o ssh_option] looks promising, if it can put sftp into a batch mode.

We handle error checking by grep on the log file looking for keywords.

After looking for a list of sftp errors, all I can find is this:

http://fixunix.com/ssh/330198-sftp-errors-messages.html

I don't even know if this is correct for the version of sftp we will use.

We don't even have an agreement regarding keys so we can eliminate storing passwords, yet they want this implimented by month end.

Thanks,
Tom

sftp should have a -b option which allows to specify a [batch] file with commands for sftp to execute. You will also probably have to set up 'password-less' authentication for scripting.

How is that different from your FTP client?

It may be useful, but perhaps not much better
than getting commands from redirected input
(like the here-document in your FTP script
fragment).

-b can be for batch mode. And it is also possible to have user name and password in the batch file although it is not highly recommended.

[Thomas Jones2]

If we can get keys installed, the -b option looks good since they want us to quit using netrc files. Plus I don't think sftp works with netrc.

Hi Thomas:

See my comments including a shell-based SFTP batch script in this thread:
