how to save the output of command in tcl/expect

hi, everyone:

I just wonder how to save the output of command, I mean everything, save as a string into a variable.

another question is I try to ls the details of a directory, but it works in the shell, not in the script.

for example
Code:
code: ls -ltr *se100* | grep ^- | tail -1 | awk ' { print $9 }'
    or spawn ls ...........................

it works in the shell, not in the script.
error message: can't read "9", no such variable.
What I want is to save the name of my file, 9 is the location of the name in the pipeline.

Thanks, guys
