Резервное копирование Cisco с помощью expect

Я хотел сделать резервную копию запущенного конфига, но не получилось, как я хотел, как мне сбросить данные в txt?

#!/usr/bin/expect -f

set force_conservative 0  ;# set to 1 to force conservative mode even if
                          ;# script wasn't run conservatively originally
if {$force_conservative} {
        set send_slow {1 .1}
        proc send {ignore arg} {
                sleep .1
                exp_send -s -- $arg
        }
}
