在linux下使用LFTP多點下載

參考 http://yurinfore.blogspot.com/2009/10/linux.html

改成可以控制下載thread數量
function pget()
{
thread=5

case $# in
1)
addr=$1
;;
2)
thread=$1
addr=$2
;;
*)
echo "usage:"
echo "pget [URL] (default thread:5)"
echo "or"
echo "pget [thread] [URL]"
exit 1
;;
esac


echo thread : $thread
echo address : $addr
cmd="pget -n $thread $addr; exit"
lftp -e "$cmd"
}
