Shell脚本错误：输入行中的参数太多

Question

有一个文件可以说List.txt它包含必须从服务器复制到机器然后删除的文件的信息。

执行shell脚本时，它读取List.txt文件，将文件名存储在变量中，将文件从服务器复制到计算机，然后删除服务器的文件。

如果文件List.txt包含多达16个文件名，那么它工作正常。

如果是List.txt包含超过16个文件会给出错误。

错误：输入线

它的任何想法太多的争论。

我怀疑这是在您的FTP客户端（或在服务器端，可能）内的mget的限制。

最好的建议是在dogetftp()函数中实际创建一个get行，每个文件在$fileNamesListStr。

例如：

dogetftp() 
{ 
    LOCAL=$1 
    REMOTE=$2 

    echo "================================================" 
    echo "==   Receiving Files From $IP   ==" 
    echo "================================================" 
    exec 4>&1 
    ftp -nv >&4 2>&1 |& 

    pid2=$! 
    print -p open $IP 
    print -p user $user $pass 
    print -p asc 
    print -p lcd $LOCAL 
    print -p cd $REMOTE 
    print -p pwd 
    print -p prompt 

    ### Begin change here. 
    for fspec in $fileNamesListStr ; do 
     print -p get $fspec 
     print -p delete $fspec 
    done 
    print -p delete $bingoFileName 
    ### End change here. 

    print -p bye 
    wait $pid2 
}
