[K12OSN] More scripting help...

[Shawn Powers]

Ok, I'm sorry to use this list as my personal scripting helpline --  
but it's the third day of school, and I'm in a real bind...  (DNS pun  
not intended)

Here's my script for changing passwords:
#!/usr/bin/expect
# script name mypasswd
set username [lindex $argv 0]
set password [lindex $argv 1]
set name [lindex $argv 2]
spawn passwd $username
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
spawn chfn -f "$name" $username
expect eof

it works, as long as I put the "name" in quotes (due to the issue of  
spaces)

In my bulk script, however, I can't seem to get the variable assigned  
correctly.  I don't know how to make it assign the whole name (both  
first and last) with the space.  Here's my bulk script:

#!/bin/bash
# script name mybulkpasswd
for lines in `cat $1`
do
username=`echo $lines | awk -F: '{print $1}'`;
password=`echo $lines | awk -F: '{print $2}'`;
name="`echo $lines | awk -F: '{print $3}'`";
mypasswd $username $password "$name";
done

Here's an example bulk file:

testuser:testpass:Test User
test1:test1:Test Account 1


Any more insight?
Thanks, and I am sorry for all my questions,
-Shawn
