Bash脚本通过FTP上传文件

Question

我正在尝试这个脚本来创建文件并上传到ftp服务器。该脚本是基于在论坛上看到的其他脚本。

    HOST=example.com #This is the FTP servers host or IP address.
    USER=ftpuser #This is the FTP user that has access to the server.
    PASS=1234 #This is the password for the FTP user.
    FILE_PREFIX=FRAME

    timestamp() {
      date +"%s"
    }

    ftp() {
        ftp -i -n $HOST << END_SCRIPT
        user $USER $PASS
        # #cd /path/to/file
        put $FILENAME
        bye

    END_SCRIPT
    }

    # # Call 1. Uses the ftp command with the -inv switches. 
    # #-i turns off interactive prompting. 
    # #-n Restrains FTP from attempting the auto-login feature. 
    # #-v enables verbose and progress. 


    # shoot picture

    while true; do
        FILENAME=${FILE_PREFIX}_$(timestamp).txt
        echo $FILENAME > $FILENAME

        echo "Subiendo $FILENAME"
        ftp

        sleep 2
    done
    EOF

当我执行脚本时，我会收到以下错误消息：

script.sh: 14: script.sh: 0:打开的文件太多

你能帮我解决这个错误吗？谢谢

将函数ftp重命名为其他内容，并在使用sleep 2之前调用它。
