Get cURL response in bash
提问by RGilkes
I have a simple bash script that uploads files to an FTP. I was wondering how to get a response from curl that I can record (error or success)?
我有一个简单的 bash 脚本，可以将文件上传到 FTP。我想知道如何从 curl 获得我可以记录的响应（错误或成功）？
eval curl -T "${xmlFolder}"/"${xmlFile}" "${mediaFTP}"
Thanks in advance
提前致谢

Given the command provided, this should suffice:
鉴于提供的命令，这应该足够了：
curl -T "$xmlFolder/$xmlFile" "$mediaFTP" ||
printf '%s\n' $?
Or, if you want to discard the error message:
或者，如果您想丢弃错误消息：
curl -T "$xmlFolder/$xmlFile" "$mediaFTP" >/dev/null ||
printf '%s\n' $?

The $? bash variable indicates success (val 0) / failure (val non 0) of the previous command. So you could do:
美元？bash 变量表示上一个命令的成功（val 0）/失败（val non 0）。所以你可以这样做：
eval curl -T "${xmlFolder}"/"${xmlFile}" "${mediaFTP}"
err=$?
if [ $err -ne 0 ]
then
echo "Failed with error code $err"
exit
fi
