獲取不等待用戶輸入的期望腳本

Question

當我嘗試運行以下期望腳本時，它只是完成運行，而不是等待用戶輸入。有人能告訴我我做錯了什麼嗎？

#!/usr/bin/expect 
puts -nonewline stdout "Enter device id:" 
flush stdout 
gets stdin id 
puts -nonewline stdout "Enter device name:" 
flush stdout 
gets stdin name 

Answer 1

期望改變Tcl gets命令，以便它不等待標準輸入;讀取線，而等待它，你需要做的，而不是gets stdin id：

# Read input to stdin 
expect_user -re "(.*)\n" 
set id $expect_out(1,string) 

Answer 2

試試這個代碼：

expect "\\$" 
puts -nonewline "please enter a swithch user: " 
flush stdout 
set userName [gets stdin] 
puts $userName 
expect "\\$" ;# without this line, the script would exit too fast 
      ;# for the "echo hello" to be sent to stdout by bash 
      ;# and thus wont be recorded
