shell遍历一个日期范围

方法1#!/usr/bin/env bash
date1="$1"
date2="$2"echo "date1: $date1"
echo "date2: $date2"
tempdate=`date -d "-0 day $date1" +%F`
enddate=`date -d "-0 day $date2" +%F`
tempdateSec=`date -d "-0 day $date1" +%s`enddateSec=`date -d "-0 day $date2" +%s`echo "####################################"
echo 'tempdate: '$tempdate
echo 'enddate: '$enddate

for i in `seq 1 300`; do
if [[ $tempdateSec -lt $enddateSec ]]; then
break
fi echo $tempdate
python pc_jibzhuanti_url.py $tempdate
tempdate=`date -d "-$i day $date1" +%F` tempdateSec=`date -d "-$i day $date1" +%s`
done这是一个倒序输出时间的脚本，需要输入两个时间参数，一个是开始时间，一个是结束时间，如输入：./pc_jibzhuanti_url_run.sh 2014-06-30 2014-06-01输出的结果是：date1: 2014-06-30
date2: 2014-06-01
