Expect script error missing close-brackets
提问by Aaron88
Hi here is my expect script:
嗨，这是我的期望脚本：
#!/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 < $no} {incr i 1} {
send -- "^[-"
}
expect -exact "\/----Enter Password----\"
expec eof
I want to send escape and hyphen character multiple times until I receive "/----Enter Password-----\ prompt. But I'm receiving following error at this line:
我想多次发送转义和连字符，直到我收到“/----输入密码-----\”提示。但我在这一行收到以下错误：
missing close-bracket
while executing
"'send -- "^[-"'
"
("for" body line 2)
invoked from within
"for {set i 1} {$i < $no} {incr i 1} {
'send -- "^[-"'
}"
(file "script_auto.exp" line 31)
I'm newbie to expect. Kindly let me know what does that error mean and how can I resolve it.
我是新手期待。请让我知道该错误是什么意思，我该如何解决。

expect is an extension of the Tcl language. In Tcl, square brackets are used for command substitution, exactly the way backticks are used in posix shells.
expect 是 Tcl 语言的扩展。在 Tcl 中，方括号用于命令替换，这与 posix shell 中使用反引号的方式完全相同。
Change
改变
send -- "^[-"
to
到
send -- {^[-}
The curly braces prevent command substitution, so the open bracket is seen as just a plain character.
花括号防止命令替换，因此左括号被视为只是一个普通字符。
