问shell怎么样从A文件夹里面提出0001——0514逐个处理后对应着编号放到B文件夹里面？

24 cut_e=`echo ${cut_b} | gawk '{print $2+100}'`

25 evt_id=`echo $cut_b | gawk '{print $1}'`

26 mkdir /home/yby/Desktop/data/AE_2023/event/0077/$evt_id

27 sac << EOF

28 cut ${b_time} ${cut_e}

29 r ${con}/00?.sac

con中逐行读取了文件0001——0514，怎么样在26行和30行分别让con中读出来的文件执行后一一对应存到里面啊
