Question

您好我想通过自动SFTP脚本将目录中的文件传输到远程服务器。我试过下面的代码。但它没有用。

#! /bin/bash
i=0
for file in *; do
    array[ $i ]="$file"
    (( i++ ))
done

expect <<EOF
spawn sftp user1@10.121.121.121
expect "user1@10.121.121.121's password:"
send "password\n"
expect "sftp>"
send "cd /user/KBACS/test\n"
expect {
    "sftp>" {
        for {set j 0} {$j < $i} {incr j 1} {
            send "put ${array[j]}\n";
        }
        send "bye\n";
    }

    EOF
}
EOF

我可以登录远程服务器。之后就会出现这样的错误。

    sftp> cd /user/KBACS/test
    sftp> missing operand at _@_
    in expression " _@_< 8"
        (parsing expression " < 8")
        invoked from within
    "for {set j 0} { < 8} {incr j 1} {
                            send "put 20171108.log\n";
                    }"
        invoked from within
    "expect {
            "sftp>" {
                    for {set j 0} { < 8} {incr j 1} {
                            send "put 20171108.log\n";
                    }
                    send "bye\n";
            }

        EOF
    }"

请帮我解决这个问题或建议任何替代解决方案。提前谢谢。

我建议您设置ssh密钥，这样您就不需要提供密码，然后在批处理模式下使用sftp

{ printf "put %s\n" *; echo bye; } | sftp -b - user@host

如果这不可行，那么你不需要结合expect和bash：expect（和Tcl）可以找出当前目录中的文件：glob

#!/usr/bin/expect -f
spawn sftp user1@10.121.121.121
expect "user1@10.121.121.121's password:"
send "password\r"
expect "sftp>"
send "cd /user/KBACS/test\r"
expect "sftp>"
foreach filename [glob *] {
    put "$filename\r"
    expect "sftp>"
}
send "bye\r"
expect eof

在期望的shell脚本中_ _ _处缺少操作数
