Shell SFTP script with password
Can someone help me out? I need a shell script that can make an sftp connection with a password - installing the keys is not an option. The scripts that I have (pasted below) throw an error saying that the command "expect" is not available. Any help would be GREATLY appreciated.
#!/bin/sh
expect << 'EOS'
spawn sftp USERNAME@ip_address:/path/
expect "Password:"
send "PASSWORD\n"
expect "sftp>"
send "put file1\n"
expect "sftp>"
send "bye\n"
EOS
#!/bin/sh
expect << 'EOS'
spawn sftp USERNAME@ip_address:/path/
expect "Password:"
send "PASSWORD\n"
expect "sftp>"
send "put file1\n"
expect "sftp>"
send "bye\n"
EOS
If you are familiar with perl, I would use that with Expect.
Or, use rsync over ssh.

I'm with noci, avoid using Expect, unless you have a bunch of interactive prompts to script.
I'm with Jan, way easier to use rsync than sftp + many times sftp is throttled + ssh/rsync runs full speed.

Noci and David - Thanks - I didn't realize you could just leave out "expect". However, the revised script still doesn't quite work - If I run the script from the command prompt, I'm still prompted for a password. Is there any way to prevent that?
#!/bin/sh
sftp [userid]@[destination.url.
[password]
put /apps/dev/data/transfer/[s
bye
EOS
#!/bin/sh
sftp [userid]@[destination.url.
[password]
put /apps/dev/data/transfer/[s
bye
EOS

A stray thought, one I cannot test at the moment, but memory suggests you still need to deconstruct the initial line. Something like,
>sftp
open <target IP address>
username
password
cd x
and so on
>sftp
open <target IP address>
username
password
cd x
and so on
sftp requires at least user@host on the commandline user is optional, then the current username is used.
And use a set of keys in stead....
Expect is not a standard command, it belongs to the tcltk family of software which can built from these sources:
http://expect.nist.gov/
Or otherwise by installing expect on yout system according to your package managers rules. (Again look for Tcl/Tk)..
Now.... why use expect if you can send it directly:
#!/bin/sh
sftp USERNAME@ip_address:/path/
PASSWORD
put file1
bye
EOS
or Alternatively:
scp file1 USERNAME@ip_address:/path/
PASSWORD
EOS
Again the whole purpose of these commands (ssh, scp, sftp) were to get rid of passwords in scripts and have sucure links (non-eaves dropping) between systems.
