我正在尝试编写一个期望脚本,它将 ssh 到服务器,发送 sudo su,然后检查 iptables 状态并将输出放在服务器上的日志文件中。下面是脚本。
1 #!/usr/bin/expect
2 exp_internal 1
3 log_user 0
4 set timeout 10
5 set password "******"
6
7 spawn /usr/bin/ssh -l subhasish *.*.*.* -p 10022
8
9 expect {
10 -re "password: " {send "$password\r"}
11 -re "$ " {send "sudo su\r"}
12 -re "[sudo] password for subhasish:" {send "$password\r"}
13 -re "# " {send "service iptables status\r"}
14 }
15 set output $expect_out(buffer)
16 send "exit\r"
17 puts "$output\r\n" >> output.log
但是在调试模式下运行时,我收到这样的错误;
expect -d testcase
expect version 5.44.1.15
argv[0] = expect argv[1] = -d argv[2] = testcase
set argc 0
set argv0 "testcase"
set argv ""
executing commands from command file testcase
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {24105}
invalid command name "sudo"
while executing
"sudo"
invoked from within
"expect {
-re "password: " {send "$password\r"}
-re "$ " {send "sudo su\r"}
-re "[sudo] password for subhasish:" {send "$password\r"}
..."
(file "testcase" line 9)
不知道我哪里出错了。它说无效的命令名称“sudo”,我猜这是因为期望不理解这些命令。如何绕过它。请帮忙。谢谢。
