只要把你的功能在这里文档中，也：

Just put the functions in your here document, too:

var="Hello World"
ssh user@host <<END
x() {
    print "x function with args=$*"
}

x "$var"
END

一些评论：

1. 您说的出口JBOSS_HOME但你永远不为这里文档中变量定义值。您应该使用出口JBOSS_HOME =$ JBOSS_HOME。 BASH将采取两个 END之间的所有文字，更换所有的变量，并将结果发送到SSH进行处理。

1. You say "export JBOSS_HOME" but you never define a value for the variable in the here document. You should use export JBOSS_HOME="$JBOSS_HOME". BASH will take all text between the two END, replace all variables, and send the result to SSH for processing.

这也意味着对方会看到 RM -f /路径/要/ JBoss的/服务器/ *登录。在这里文件的最后一行分配给 JBOSS_SERVER 在无影响（至少还没到code清理（））。

That also means the other side will see rm -f /path/to/jboss/server/*.log; the assignment to JBOSS_SERVER in the last line of the here document has no effect (at least not to the code in cleanup()).

如果你想通过 $ 未修改到远程服务器，您有来逃避它\\ ： RM -f \\ $ JBOSS_SERVER /日志/ *。登录

If you want to pass $ unmodified to the remote server, you have to escape it with \: rm -f \$JBOSS_SERVER/log/*.log

您永远不会调用清理（）

有一个} 后失踪返回0 来完成的定义 deployapp（）

There is a } missing after return 0 to finish the definition of deployapp()

有可能有其他问题为好。运行带有的bash -x 剧本，看看有什么外壳实际执行。您还可以添加此文档中回声命令来查看哪些变量的值，也可以添加设置-x 在清理（）来得到相同的输出与的bash -x 但是从远程端。

There may be other problems as well. Run the script with bash -x to see what the shell actually executes. You can also add echo commands in the here document to see what the values of the variables are or you can add set -x before cleanup() to get the same output as with bash -x but from the remote side.
