Shell脚本错误:输入行中太多的参数

Question

有一个文件，比如List.txt，它包含文件的信息，这些信息必须从服务器复制到另一台机器，然后删除。

当shell脚本执行时，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另一台机器，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，那么它运行良好。

如果List.txt包含超过16个文件，则会产生错误。

错误:输入行中的参数太多

任何关于它的想法。

我怀疑这是mget客户端(或服务器端)中的一个限制。

最好的建议是在$fileNamesListStr函数中每文件实际创建一个dogetftp()行。

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
}
