does the expect script tries to match for everyline on the screen irrespective of the prompts???
After the installer begins.. it displays various lines before the first expect.
But the script tries to match for every line that is displayed before the 1st and timeouts.
1)Why does it tries to match for every lines that is out in the screen?
when it finds the actual matches - the send is passed
2) and also it appends the previous results to next and the expect statement is appended recursively
because of this the expect statements gets varying including the newlines and the order is not maintained.

Hey all. Sometimes I'm tasked to change some router configs for the entire network (over 3,000 Cisco routers). Most of the time its a global config parameter so its done with a loop and an IP list as its the same configuration change for all routers. This is working OK.

expect_expectl
EXPECT_EXPECTL(3) 1 EXPECT_EXPECTL(3)expect_expectl - Waits until the output from a process matches one of the patterns, a specified time period has passed, or anEOFis seenSYNOPSIS
int expect_expectl (resource $expect, array $cases, [array &$match])
DESCRIPTION
Waits until the output from a process matches one of the patterns, a specified time period has passed, or an EOF is seen.
If $match is provided, then it is filled with the result of search. The matched string can be found in $match[0]. The match substrings
(according to the parentheses) in the original pattern can be found in $match[1], $match[2], and so on, up to $match[9] (the limitation of
libexpect).
PARAMETERS
o $expect
- An Expect stream, previously opened with expect_popen(3).
o $cases
- An array of expect cases. Each expect case is an indexed array, as described in the following table:
