老系统玩转文本日志之日期范围随便查

函数格式版：

for day in $(seq 17 23)

do

folder=2017-09-${day}

grep "clickid=807c98" ${folder}/* >> "clickid_807c98_2017-09-17_23_conver.txt"

done

一行版：

for day in $(seq 17 23); do folder=2017-09-${day}; grep "clickid=807c98" ${folder}/* >> "clickid_807c98_2017-09-17_23_conver.txt"; done
