If you are going to use a script like this to head the top of a file list, wget the url, and then use sed -i to remove the first line, you should check the bash error code before you remove the url from the list:
url=`head -n1<nobr> <wbr></nobr>.wget-list`
wget -c $url ERRORCODE=$? if [ $ERRORCODE -eq 0 ]; then
sed -si 1d<nobr> <wbr></nobr>.wget-list else
echo "ERROR: could not get $url" 1>&2
exit $ERRORCODE fi
Otherwise, if wget fails, (not uncommon if server temporarily overloaded or down, etc) you remove the url you wanted to download from your DL list but you don't get your file.
