使用這裏面的函數文件

Question

我有一個腳本，裏面有一些主體用來執行的函數。現在，我想在3個遠程unix機器上運行這個腳本。這是最好的方法嗎？ 最重要的是，我不寫遠程連接的第二個腳本。一切都應該在這一個腳本里面。

我試過heredoc與SSH，這是不工作，因爲大功能！

移動的定界符文本的功能。它可能需要對代碼結構進行一些更改，但它會起作用。

ssh app01.datacentre.private <<EOD 
hostdatefunc() { 
echo \$(hostname) \$(date) 
} 
hostdatefunc 
EOD 

你會得到遠程服務器的主機名和日期，不是你的。作品。愚蠢的例子，但概念證明。
