Question

嗨，这是我的期望剧本：

#!/usr/local/bin/expect -f
set force_conservative 0  ;# set to 1 to force conservative mode even if
                          ;# script wasn't run conservatively originally
if {$force_conservative} {
        set send_slow {1 .1}
        proc send {ignore arg} {
                sleep .1
                exp_send -s -- $arg
        }
}

set timeout -1
spawn $env(SHELL)
match_max 100000
send -- "ssh IP_addr\r"
expect -exact "password: "
send -- "something\r"
expect -exact "\r"
#expect -exact "Entering server port, ..... type ^z for port menu."
send -- "\r"
expect -exact "login: "
send -- "admin\r"
expect -exact "password: "
send -- "something\r"
expect -exact "something > "
send -- "reboot\r"
expect -exact "REBOOT THE SYSTEM? (y or n): "
send -- "y\r"
expect -exact "SYSTEM REBOOTING!\r"
set no 20
for {set i 1} {$i < $no} {incr i 1} { 
    send -- "^[-"   
}
expect -exact "\/----Enter Password----\\"
expec eof

我想多次发送转义和连字符，直到收到“/ ----输入密码----- \提示符。但我收到以下错误：

missing close-bracket
            while executing
        "'send -- "^[-"'
        "
            ("for" body line 2)
            invoked from within
        "for {set i 1} {$i < $no} {incr i 1} {
                'send -- "^[-"'
        }"
            (file "script_auto.exp" line 31)

我是新手，期待。请告诉我这个错误意味着什么，我该如何解决它。

Answer 1

expect是Tcl语言的扩展。在Tcl中，方括号用于command substitution，与posix shell中的反引号一样。

更改

send -- "^[-"

到

send -- {^[-}

花括号可以防止命令替换，因此开括号看起来只是一个普通字符。

期待脚本错误缺少关闭括号
