Macos 预期返回错误“；选项需要一个参数"；当给出论据时

我有以下代码：

#!/bin/sh
if [ "upload" == $1 ];then
expect -c <<'END_EXPECT'
set timeout -1
spawn sftp -i /Users/myuser/.ssh/private.key root@dev.site.org
expect "sftp>"
send "put dirname $0/$2/$3 /var/www/localhost/htdocs/dev1.site.org/$2/$3\r"
expect "%100"
send "quit\r"
expect eof
END_EXPECT
elif [ 'download' == $1 ];then
expect -c <<'END_EXPECT'
set timeout -1
spawn sftp login_name@1.2.3.4
expect "[Pp]assword:"
send "login_password\r"
expect "sftp>"
send "get /remote_path/$2/$3 dirname $0/$2/$3 \r"
expect "%100"
send "quit\r"
expect eof
END_EXPECT
fi

我在OSX 10.9中。为什么它不起作用？我过去从未使用过expect…

在此处文档中传递expect脚本时取出

-c

此外，您引用了here doc terminator一词：

非常感谢。。。你是对的。根本不需要使用expect。我已经向我正在使用的插件的github站点提交了一个问题（）问题：有没有办法让ssh连接处于活动状态？我的服务器限制在600秒的时间内最多从同一台服务器连接5次。所以对于发展来说这是没有用的。。。如何使连接保持活动状态并在以后重新使用？谢谢，如果你能帮我…强烈建议你问一个新问题，这样其他人就会看到。首先想到的是和你的系统管理员谈谈。谢谢Glenn。。实际上我管理服务器，所以我增加了连接数。。。但这不是一个好的做法，我不喜欢它。。。我会的。谢谢
