Need help to append and get output from Shell script to retrieve output from expect

  • Jesse

    I have written a for look in ksh that calls expect to login to multiple servers. I execute shell script to loop through Server list. Within loop I call out expect script to log into each server send uname -ns command to get hostname and OS. I have mix of Solaris, Linux, HP servers and would like to get output of each servers. Now how do I get output sent to primary server that I run script from. Here is what I have.

    Shell script


    for var in cat hostlist
    expect.uname $var;

    Here is my expect.uname script


    set timeout 20
    set server_name [lindex $argv 0]
    spawn ssh "$server_name"
    set output [open "outputfile.txt" "a+"]
    sleep 2
    send "uname -ns\n"
    expect "*$"
    set outcome $expect_out(buffer)
    send "\r"
    puts $output $outcome
    send "exit\r";

    I loop through all the servers correctly.
    how do I retrieve the outputfile.txt and did I do this correctly?

    I'm very new at expect
