Question

我试图做一个聪明的＆＃34;升级filebot jar文件的脚本但我遇到了一些问题，第一个问题是，如果我使用curl比较在线文件和本地文件，有时我收到的http_code是304，有时是200，这不是很有帮助！！首先我使用stat -c %Y ...生成一个时间戳文件但问题不在这里，所有工作除此之外，有时返回200有时304，我认为这不是代码问题，但也许有人知道更好的方法来做到这一点

curl -s -k http://sourceforge.net/projects/filebot/files/filebot/HEAD/FileBot.jar -z "$(date --rfc-2822 -d @$(</opt/usr/share/fbot/FileBot.jar.timestamp))" -o /opt/usr/share/filebot/FileBot.jar -L -w %{http_code}

仅仅因为我认为这是一个正常的＆＃34;错误，我无法解决它，我想抓住http_code，如果是200做一些stuf，如果是304其他东西和其他......

但我无法在不重新下载文件的情况下向http_code声明变量

我有这段代码

        if [[ "$(curl -s -k $FILEBOTURL -z "$(date --rfc-2822 -d @$(<$FILEBOTTIMESTAMP))" -o $TMPFILE -L -w %{http_code})" == "200" ]]; then
        echo "yep!"
        get_timestamp
    else
        echo "I can't download the FileBot jar, try again later"
        exit
    fi

正如您在理论上所看到的，如果http_code为200，则下载并升级文件，仅当http_code为304时，文件已经更新。所以我的想法是卷曲一次我需要并将http_code分配给一个varialbe，然后如果变量是200等等......

我试图这样做

if [[ "HTTPCODE=$(curl -s -k $FILEBOTURL -z "$(date --rfc-2822 -d @$(<$FILEBOTTIMESTAMP))" -o $TMPFILE -L -w %{http_code})" == "200" ]]; then

但是HTTPCODE是空的，所以任务失败了！

有任何想法或建议吗？

Ok tnx rednoah，您如何看待这个？我试图让它变得直观＆＃34;因此，如果下载文件不正确或其他不进行更新
