ssh進入DC的時間時鍾服務器后，如何在腳本中觸發腳本？

Question

因此，我有一個腳本，其目的是：

1. 詢問DC號和時鍾號

2. 登錄上述DC的時鍾服務器

3. 登錄后，它打算在我的腳本中運行一個單獨的腳本，該腳本將更新上文所述的時鍾編號。

我的問題是，一旦觸發腳本，腳本便會按預期登錄服務器，提示我輸入用戶ID，然后在出現“ xterm”時必須按“輸入”。 之后，應該運行更新腳本，但是不會運行更新腳本，它位於命令行中。

我退出服務器后，然后它將運行更新腳本，但失敗，因為跳轉框中不存在更新腳本。

我的問題是，腳本登錄到服務器后，如何如我所願地在時鍾服務器內部觸發腳本？ 謝謝。

腳本如下：

#!/bin/bash -x
export LANG="C"

echo ""

echo "-----------------------------------------------------------------------------------------------------------------------------------------"

$tcupd #Runs update script

echo "-----------------------------------------------------------------------------------------------------------------------------------------"

echo ""

sleep 2

echo "If prompted to engage NOC due to Timeclock not being on the network, send the ticket to DC Networking"

echo ""

echo "OR"

echo ""

echo "If the script completed successfully, and the Timeclock was updated, you can now resolve the ticket"

Answer 1

您必須在ssh會話中而不是在以下命令中運行命令：

echo "Preforming Timeclock update on Timeclock=$TMC, at DC=${DC}"

echo ""

echo "-----------------------------------------------------------------------------------------------------------------------------------------"

###### $tcupd #Runs update script
/usr/bin/dzdo -u osedc /bin/ssh -qo PreferredAuthentications=publickey root@$tnaserver /bin/bash -c /u/applic/tna/shell/tc_software_update.sh tmc${TMC}.s0${DC}.us REFURBISHED

echo "-----------------------------------------------------------------------------------------------------------------------------------------"

echo ""

sleep 2

echo "If prompted to engage NOC due to Timeclock not being on the network, send the ticket to DC Networking"

echo ""

echo "OR"

echo ""

echo "If the script completed successfully, and the Timeclock was updated, you can now resolve the ticket"

從man ssh可以看到ssh [-46AaCfGgKkMNnqsTtVvXxYy] ....... destination [command] 。 如果未指定[command]則ssh運行遠程登錄命令腳本，例如xterm。 您可以在此處或此處閱讀更多信息 ，或者只是瀏覽google。
您需要考慮如何以及將哪種環境變量傳遞給遠程計算機，並記住正確封裝這些變量，以使它們在您或遠程計算機上得到擴展。
