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

nwvolinfo

NWVOLINFO(8)							     nwvolinfo							      NWVOLINFO(8)

NAME

       nwvolinfo - Diplay info on NetWare Volumes

SYNOPSIS

       nwvolinfo [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -v volume ] [ -N ]

DESCRIPTION

       nwvolinfo displays information on a NetWare Server Volume.

       nwvolinfo  looks  up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more informa-
       tion. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.

OPTIONS

       -h
	  -h is used to print out a short help text.

       -S server
	  server is the name of the server you want to use.

       -U user
	  user is the user name to use for login.

       -P password
	  password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server,  nwvolinfo
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -v volume
	  The volume name to be used. Defaults to 'SYS'.

       -N
	  Display the information in numeric-only format for use in a pipe.
