Slashes as escape characters don't seem to work...
Thanks for taking the time to offer your suggestion sysgate. I just tried modifying the script to use both forward and backward slashes, neither did what I wanted, but they had very different results...

When I used a backward slash (\) I got the following rsync command out of the expect script - the escape character seems to have just nulled the $ so I get the variable name inserted, rather than the variable's value:

Code:
spawn time rsync -a -z -E --exclude-from=/tmp/exclude.txt --progress --partial --timeout=30 -e ssh /Users/admin/Documents $login@time-od.csf.bc.ca:

When I used a forward slash (/) I got the following,which is the same as before, adding an unwanted [tab]:
Code:
spawn time rsync -a -z -E --exclude-from=/tmp/exclude.txt --progress --partial --timeout=30 -e ssh /Users/admin/Documents /	est_student@time-od.csf.bc.ca:

I even tried entering both / and \ in front of test_student right in the original command and that doesn't help either... / just adds the / in front of test_student (so does get rid of the [tab], but also doesn't give the right command) and \ doesn't seem to do anything, still end up with [tab]est_student.

What IS interesting to me is that I entered the server as 'time' simply to test if that 't' was also coming out as a [tab] - as you can see from the results, it isn't - I suspect because it's immediately behind the @ character. So perhaps this is something to do with having the variable right after a space.

So back to the drawing board. Any other ideas?
