Firstly thank you so much for replying....
actually i am new to expect:

I am able to execute the commands automatically using expect for telnet session.

Now my requirement is:
as of now those commands are all valid one's, which i am seeing on output but

now i want them to automate for all invalid conditions like..
when commands are unexpectedly typed wrong by human manually, it show corresponding error message...so now i want the same effect using expect automatically for all valid commands which i have done it for.

the attachment is what i have written sample code for randomizing passwords ..i tried this to get idea to my actual problem. that's it
please if you again not clear on question: please do ask i will try to elaborate it clearly once again

thank you

Again, where is your code? Please don't use attachments to post your code if it's basically just a few lines, and especially do not write your questions into the attachment. Instead, give a proper explanation of what you're doing, what you're trying to do, where you're stuck, and what you've tried.

here is my code:

Code:
#!/usr/local/bin/expect —f
proc insertchar {c} {
global password
set password [linsert $password \
[rand [expr 1+[llength $password]]] $c]
}
set _ran 5
proc rand {n} {
global _ran
set period 233280
set _ran [expr ($_ran*9301 + 49297) % $period]
expr int($n*($_ran/double($period)))
}
send_user "rand n\n"
send_user "insertchar c\n"
set minnum 2
set minlower 4
set minupper 4
expect "$ " 
set pwd "vani"
set password [join "$pwd" ""]
for {set i 0} {$i<$minnum} {incr i} {
send "$password [rand 10]\n"
}
for {set i 0} {$i<$minlower} {incr i} {
send "$password [format "%c" [expr 0x61 + [rand 26]]]\n"
}
for {set i 0} {$i<$minupper} {incr i} {
send "$password [format "%c" [expr 0x41 + [rand 26]]]\n"
}

result for above code is:
Code:
rand n
insertchar c
vani 4
vani 8
vani n
vani v
vani o
vani j
vani A
vani E
vani Z
vani L

but i want the letters to be inserted in to the string by picking up randomly like :
Code:
v1ani
Vani
Va1ni

so that i can test commands for all invalid cases also.
