一个导出redis有序集合sorted-sets的shell脚本

1. 经过keys匹配须要导出的有序集合名称，这些集合命名格式为：*_010_09/Dec/2015
2. 依次经过zscan导出有序集合中的数据，并分别保存

#/bin/sh
zset_pattern=”*_010_09/Dec/2015″
keys=`redis-cli keys $zset_pattern`
for k in $keys;do

_date=`echo “$k”|awk -F”_” ‘{print $3}’|awk -F”/” ‘{print $3″_”$2″_”$1}’`
out=`echo “$k”|awk -F”_” ‘{print $1″_”$2}’`”_$_date.txt”
cursor=0

batches=0
while [ 1==1 ];do

reply=`redis-cli zscan $k $cursor`
cursor=`echo “$reply” | head -n 1`

pairs=`echo “$reply”|tail -n +2`

[ $cursor -eq 0 ] && [ $batches -gt 0 ] && break
batches=`expr $batches + 1`

skip_key=0
echo “$pairs”|while read ms

do

#skip empty members
[ “$ms” == “” ] && skip_key=1 && continue
[ $skip_key -eq 1 ] && skip_key=0 && continue
if [ “$m” == “” ];then

m=$ms && continue

fi
if [ “$s” == “” ];then

s=$ms
echo “$m $s” >> $out
m=”” && s=””

fi

done

done

done
