后台执行的方法：disconnect

#!/usr/bin/expect

spawn openvpn --config ./test.ovpn
expect "*Username:"
" X3 z% y4 V! Esend "root\r"

expect "*Password:"
" w9 i! x- a+ r+ y* Psend "passwd\r"

if [fork]!=0 exit
disconnect

+ ^" d6 U4 F; @+ x

传递参数的方法：set name [lindex $argv 0]

#!/usr/bin/expect

if { $argc != 2 && $argc != 1 } {
& v+ j+ n1 a8 {    send_user "Usage:auth username \[password\]\n"
    send_user "\tthe default password equals 0000\n"

set name [lindex $argv 0]

    set pass [lindex $argv 1]
