For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
logging certain portions of output

Posted by gurudatt (gurudatt), 18 February 2008
hello,

1. As i am automating a test plan i need to log the output and do a comparison for generating a output. If i use expect_out(buffer) then i get everything that gets printed on the console even before the -> prompt.
For eg: when i start a telnet session i get the message "Welcome to Microsoft Client ..." Even this is stored in the buffer.
My question is "How do i get to log the output once it starts issuing the commands on obtaining the -> prompt.?

The code is as shown:
set id [spawn telnet 3.235.116.62]

expect -re "->"{
send "envShow\r"
}

set file1 [open "/file.pid" "w"]
puts $file1 $expect_out(buffer)
close $file1

I need to store only the output after the "envShow" command is issued.


2. I have also observed that even the buffer does not contain the entire output that is obtained on the console. what might be the reason for this?

Firstly, the expect_out buffer is limited in capacity and you'll do better to expect the response line by line rather than up to the next prompt.

And once you've done that, changing log_user between lines will provide you with som eof the fine gradation that you're looking for on selecting output.  Further data selection within a line can be done with standard Tcl tools such as regexp
