Expect/Tcl help

hi, I am new in Expect.

I have a question about expect timeout.

suppose I have a structure of

expect { ".."{
send"............"}
timeout{
...............
}
}

The silly question is if I reach timeout, how can I store the error message showing on the screen to a variable or written into a file?

the expect_out(buffer) works if the expect condition succeed, not work for timeout

any tips? Thanks

not sure if it will work but you could try setting the entire expect call to a variable

VAR1="expect ..."

and then calling it:

VAR2=`$VAR1`

then it's output would be in $VAR2. Perhaps.

what I meant is expect_out(buffer) stores everything up to expect reached; I wanna store some error message up to the timeout reached.

for example, I might have 100 test commands to send, only 95th command timeout, the rest succeeds.
I only wanna produce the details of 95th command from the screen into a log, neglect the rest, I don't wanna write entire history into a file.

is there any way to do this?

thanks
