curl 脚本 - 等待下载完成

curl 脚本 - 等待下载完成

下面是我每天用来从网站下载文件的脚本的一部分。然而最近他们增加了下载文件的速度限制。我增加了睡眠时间,但其他一切都花费了太长的时间,有很多文件需要下载,有些文件非常小。

我想删除sleep等待时间或将其设置得很低并修改脚本,以便它将等待文件完成下载

编辑:

我找到了较大文件未完成下载的原因。Failure when receiving data from the peer我怎样才能解决这个问题?我读过切换到 wget 是最好的选择,但是这个脚本如何与 wget 一起工作?

#check directories are empty, not empty if there was a problem last time
cd /home/user/upload
if [ "$(ls -A /home/user/upload)" ]; then
#     echo 'Directory not empty error for csv manipulation' | /bin/mailx -s "Server scrapeandcleandomains error" use
     echo "$(date) Directory /home/user/upload not empty for csv manipulation"  >> /home/user/logfile
     exit 1
     else
     echo $(date) starting normal >> /home/user/logfile
fi

#create yesterday variable
yesterday=$(echo  $(date --date="$1 - 2 days" +"%Y_%m_%d" ) )
#$(date --date="-2 day" +"%Y_%m_%d")







#download .csv.gz files (old wget command) OBSOLETE!!!!!
#cd /home/user/upload
#wget -R html,"index.*" -A "$yesterday*.csv.gz" -N -r -c -l1 -nd --no-check-certificate --user USERNAME --password PASSWORD -np http://www.websitedownloadfrom.com/sub/
#exit 1

#download index and sanitize > index2.tmp
cd /home/user
curl -u "USERNAME:PASSWORD" -k  http://www.websitedownloadfrom.com/sub/ -o index.html.tmp
links -dump index.html.tmp > /home/user/index.tmp
#this will work until 2049 ONLY!!
sed -i '/20[1-4][0-9]/!d' index.tmp
sed -i '/\[DIR\]/d' index.tmp
for i in {1..50} ; do
   sed -i 's/  / /' index.tmp
done

awk -F" " '{ print $3 }' index.tmp > index2.tmp
sed -i "/^${yesterday}/!d" index2.tmp







#download .csv.gz files according to index2.tmp
while read F  ; do
    cd /home/user/upload
    curl -u "USERNAME:PASSWORD" -k  http://www.websitedownloadfrom.com/sub/$F -o $F &
    sleep 80
done < /home/user/index2.tmp

sleep 60

#check that we downloaded something
cd /home/user/upload
if ! [ "$(ls -A /home/user/upload)" ]; then
    echo 'nothing downloaded from upload'  >> /home/user/logfile
    rm -f /home/user/upload/*
    rm -f /home/user/index.html.tmp
    rm -f /home/user/index.tmp
    rm -f /home/user/index2.tmp
    exit 1
fi

答案1

删除该sleep 80命令以及紧邻其之前的命令&中的。curl删除&将使脚本等待curl下载完成,然后再继续进行下一次循环。
