Expect script problem
Hello all you scripting Gurus,

I have an expect script that gets called from an AppleScript Studio app that basically takes arguments for user name, password, and server address and then calls rsync. Everything works wonderfully, EXCEPT (there had to be one of those) if the user name starts with a t, such as "test_student", the t gets converted to a 'tab' and I instead get "[tab]est_student", which obviously won't authenticate properly.

In the following code, the problem happens at the end of the spawn line, the $login variable has the problem (although I haven't tested to see if $server and $password variables have the same problem).

I guess my question is if there is a way to make it so that expect just enters the text and doesn't try to do fancy [tabs] and such? Is there a best practice in a script like this to make sure that doesn't happen?

Thanks in advance for any help offered.

Jeff

The script is as follows:

Code:
#!/usr/bin/expect --

# Student Backup Script
# 
# Purpose:      Based on provided login name, password and server, 
#				backup the user's Documents folder.
# Requires:     TCL and Expect extension
# Author:       Jeff Dyck
# Date:         12/18/2007
#
#               Usage format is ExpectBackup.sh username password server

# Bring in the variables...

set timeout 20

set localUser [exec whoami]
set login [lindex \\$argv 0]
set password [lindex \\$argv 1]
set server [lindex \\$argv 2]
set mode [lindex \\$argv 3]

# Begin syncronization...

spawn time rsync -a -z -E --exclude-from=/tmp/exclude.txt --progress --partial --timeout=30 -e ssh /Users/$localUser/Documents $login@$server:

expect {
       "(yes/no)?"  { send "yes\r"; exp_continue}
       "?assword:"  { send "$password\r"; exp_continue}
       }
       
# Wait for rsync to finish.
# expect eof

# Done.

exit 0

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
