遍历下载所有rpm包
可以用来模拟高负载

#!/bin/bash

then
	rm -rf $rpmFile

wget $rpmUrlPath
rpmListFile=/rssp/code/rpm_list.txt
if [ ! -f $rpmListFile ] 
then
	touch $rpmListFile
fi

cat index.html | grep -Eo ">.*.src.rpm"|awk 'BEGIN{FS=">"} {print $7}' > rpm_list.txt
for line in `cat $rpmListFile`
do
    wget -bc ${
