Question

我有一个令人烦恼的问题似乎导致无限循环，我无法解决原因。如果我调用以下函数，它会在屏幕上无限地重复yes / no选项，直到我崩溃。

AuditUpload() {
    clear
    echo "Audit report generated successfully"
    echo " "
    echo "Do you wish to upload qhub_audit.csv? (1 = Yes/2 = No):"
    sleep 1
    select yn in "Yes" "No"; do
    case $yn in
        Yes ) AuditUploader; Auditvi; exit;;
        No ) echo "Upload cancelled"; Auditvi; exit;;
    esac
    done
}

我把睡眠放进去看看它是否会解决这个问题，但它仍然会做同样的事情。这个问题似乎是非常间歇性的，每次都不会发生。这个脚本是用korn shell（ksh）编写的。

AuditUploader功能：

AuditUploader() {
echo "Uploading qhub_audit.csv to $HOST..." 
curl -v -T qhub_audit.csv -# ftp://xxxxxxxx:xxxxxxxxx@xxxxxxxxxxxxx.com/
    if [ "$?" -ne "0" ]
    then
        echo "ERROR: Cannot upload qhubload.csv" 
        exit
    else
        clear
        echo "qhub_audit.csv has been put on $HOST successfully"

        tput cup 5 5
        echo "Copy and paste this link into internet explorer to download:"
        tput cup 7 5
        echo "ftp://xxxxxxxx:xxxxxxxxx@xxxxxxxxxxxxx.com/qhub_audit.csv"
        read LINK
    fi
}

Auditvi功能：

Auditvi() {
clear
echo "Do you wish to view qhub_audit.csv? (1 = Yes/2 = No):"
sleep 1
    select yn in "Yes" "No"; do
    case $yn in
    Yes ) vi qhub_audit.csv; exit;;
    No ) exit;;
    esac
done

}

经过一段时间的游戏后，只要'curl'命令返回一个特定的错误，阻止kill $$正常工作，它就会循环播放。我将kill $$替换为exit 1并相应地修改了其他功能。如果FTP失败，我还要使用kermit。无论如何，这就是我现在的代码：

#########################################
# Upload quotehub audit report function #

AuditUploader() {
    echo "Uploading qhub_audit.csv to $HOST..." 
    curl -v -T qhub_audit.csv -# ftp://$USER:$PASSWD@$HOST/ -m 10
        if [ "$?" -ne "0" ]
            then
            echo "ERROR: Cannot upload qhubload.csv via FTP" 
            if [ ${term} = "tty1A" ]
                then
                echo "Attempting to download to modems server..."
                wermit -s qhub_audit.csv
                if [ $? -ne 0 ]
                    then
                    echo "Cannot upload to modems either!"
                    echo "This file will have to be downloaded manually"
                    exit 1
                else
                    clear
                    echo "qhub_audit.csv has been put on modems server successfully"
                    tput cup 5 5
                    echo "Copy and paste this link into START -> RUN to download:"
                    tput cup 7 5
                    echo "\\\\\\xxxxxxxx\download\general\qhub_audit.csv"
                    read LINK
                fi
            else
                echo "Upload failed!"
                exit 1

再次感谢各位帮助。

无效循环是/不是ksh
