我试图编写一个通过SSH连接到Linux的脚本，并允许从那里交互控制思科设备; 完成设备控制后，我也想退出shell。
我有SSH密钥，不需要密码来连接。 go下面的代码是一个Bash脚本，通过SSH / Telnet连接到目标设备。
我到目前为止所做的是：
#!/usr/bin/expect set arg1 [lindex $argv 0] spawn ssh -p 24 my_username@my_linux.domain.com expect "#" send "go $arg1 \n" expect "sername:" send "my_username\n" expect "assword:" send "my_password\n" interact expect "root@my_linux:~#" send "logout\n" expect "my_username@my_linux:~ $" send "logout\n" interact
我退出shell时出现的错误是：
Connection to my_linux.domain.com closed. expect: spawn id exp4 not open while executing "expect "root@my_linux:~#"" (file "./aaa" line 11)
我已经解决了这个问题：
#!/usr/bin/expect set timeout -1 set arg1 [lindex $argv 0] spawn ssh -p 24 my_username@my_linux.domain.com expect "#" send "go $arg1 \n" expect "sername:" send "my_username\n" expect "assword:" send "my_password\n" expect "#" interact timeout 5 return send "\n" expect "root@my_linux:~#" send "exit\n exit\n" interact
说明：我添加了几行：
# This prevents commands from timing out (default timeout is 10 seconds). set timeout -1 # When I type something, the timeout is ignored, but when I'm not typing, # it waits 5 seconds and then continues. interact timeout 5 return send "\n" expect "root@my_linux:~#" send "exit\n exit\n"
希望能帮助任何人
