Expect Script Example
The following provides a simple Expect script example with no timeouts and no error checking
using telnet instead of SSH.
#!/usr/local/bin/expect -f
#
# (Portions of) this Expect script (were) was generated by autoexpect on
#
Tue Nov 21 08:45:11 2006
# Expect and autoexpect were both written by Don Libes, NIST.
#
# Note that autoexpect does not guarantee a working script.
It
# necessarily has to guess about certain things.
Two reasons a script
# might fail are:
#
# 1) timing - A surprising number of programs (rn, ksh, zsh, telnet,
# etc.) and devices discard or ignore keystrokes that arrive "too
# quickly" after prompts.
If you find your new script hanging up at
# one spot, try adding a short sleep just before the previous send.
# Setting "force_conservative" to 1 (see below) makes Expect do this
# automatically - pausing briefly before sending each character.
This
# pacifies every program I know of.
The -c flag makes the script do
# this in the first place.
The -C flag allows you to define a
# character to toggle this mode off and on.
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
}
}
#2) differing output - Some programs produce different output each time
# they run.
The "date" command is an obvious example.
Another is
# ftp, if it produces throughput statistics at the end of a file
# transfer.
If this causes a problem, delete these patterns or replace
