two question about expect srcipt

Hi experts,

I have two question about expect script

questions 1

send "tar -xjvf a.tar\r"
send "ifconfig\r"

I want to know if it just run "ifconfig after "tar -xjvf a.tar complete. or the two cmd run at the same time



question 2

after I use the expect to ssh to the target pc (hostname=intel_server)
I want to run expect "intel_server" but, I don't know it's hostname called "intel_server" before, I know run "hostname" on the target pc after to get it, but how to let expect to get it then I can run expect "intel_server"

Question 2

Not sure what you are looking for here - but, from the Expect Wiki page

Quote:
Every time an Expect operation is completed, the results are stored in a local variable called $expect_out. This allows the script to harvest information to feedback to the user, and it also allows conditional behavior of what to send next based on the circumstances.
