Don Cragun is right, rsync would be the solution of first choice.
But still, if this is ruled out somehow for some reason we have yet to find out:

If you do not need to check for connectivity then all the better. But in your threads title and the first post you mentioned you have to use "expect" and this can conceivably only be to transmit passwords. If you can guarantee somehow your ssh-keys can always be readily exchanged (though i'd still check that before i'd base my procedures on that) you can simply use ssh to remote-execute any command(s) you want and that would probably be a cleaner solution than using expect to initiate a pseudo-interactive ssh-session.
If you need to remotely execute arbitrary commands then you might want to do it this way (sketch):
Again, I'd check if indeed the keys are exchanged by including the function i showed you and call it somewhere inside the loop as part of my errror checking, but that is up to you. You should be able to build your custom routine around the shown mechanism pretty easily.
Hi, I'm writing a shell script that calls a few commands that prompt the user for two simple yes/no questions. if the answers are consistent (the first is a yes, the second is a no), what would my expect script look like? Google is only giving me answers for scripts where I telnet or ssh. right now... (3 Replies)
And not to start. I can compare files, that's easy. The problem is that I compare files in a directory, and check if these files exist in another directory. The problem is that the file names are not the same. So I have to compare with "md5sum" or something similar. How I can do?
All this in... (7 Replies)
I was wondering if anyone could provide some assistance. I trying to run an expect script within bash and get the results of a variable called RESULT.

I'm having trouble with some automated sftp pulls. I'm using expect inside bash scripts and spawning SFTP. Some times the expect seems bog down.

I'm trying to think of a way to compare two boxes and make sure their files will be the same. There may be extra files on one side and some on the other.

scp
SCP(1) BSD General Commands Manual SCP(1)NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ...
[[user@]host2:]file2
DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
rity as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be
made explicit using absolute or relative pathnames to avoid scp treating file names containing ':' as host specifiers. Copies between two
remote hosts are also permitted.
The options are as follows:
-1 Forces scp to use protocol 1.
-2 Forces scp to use protocol 2.
-3 Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the
two remote hosts. Note that this option disables the progress meter.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode (prevents asking for passwords or passphrases).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-c cipher
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-F ssh_config
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-i identity_file
Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to
ssh(1).
-l limit
Limits the used bandwidth, specified in Kbit/s.
-o ssh_option
Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no
separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-P port
Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already
reserved for preserving the times and modes of the file in rcp(1).
-p Preserves modification times, access times, and modes from the original file.
-q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).
-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.
-S program
Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
EXIT STATUS
The scp utility exits 0 on success, and >0 if an error occurs.

scp is based on the rcp(1) program in BSD source code from the Regents of the University of California.
