如何在bash的ssh Expect腳本中自動執行ctrl + d操作？

Question

我有一個用例，在通過ssh連接到主機后需要執行命令。 命令執行后，我需要執行Ctrl-D和Ctrl-M，以便可以發出其他命令。

我嘗試使用EOF，但它完全關閉了會話。

expect << EOF
spawn ssh -o StrictHostKeyChecking=no LocalCOMUser@$nodeIp -p $ssh_port

expect {
         "password:" {}
          timeout { send_user "Timed out in ssh connection" ;exit 1}
}

send "p@ssword\r"
expect {
         ">" {}
          timeout { send_user "Timed out in ssh connection" ;exit 1}
}

set timeout 120
send "mml\r"
expect {
         "<" {}
          timeout { send_user "Timed out in ssh connection" ;exit 1}
}
send "$command1\r"
expect {
         "<" {}
}
send "exit;\r"
expect {
         ">" {}
          timeout { send_user "Timed out in ssh connection" ;exit 1}
}
send "exit\r"

EOF

需要一個執行Ctrl-d的命令。

您可以通過發送^ D / ␄字符來模擬按Ctrl-D：

send "\x04"
