如何删除除此文件名的最新文件之外的最旧文件？

我想要这个结果
ls
10MX232 .201805120846.txt
1465LY1 .201805111419.txt
17NX232 .201801300058.txt
最佳答案
run_path=./testlog/
declare -a file_nm
declare -a file_id
declare -i x
declare -i id_count
x=0
ls -1 $run_path | while read -r idpc; do
x+=1
idpc2=$(echo $idpc | cut -c1-7)
file_id[$x]=$idpc2
file_nm[$x]=$idpc
id_count=$(ls -l $run_path${file_id[x]}* | grep -v ^l | wc -l)
if [ "$id_count" -ge 2 ];then
rm $(echo "$run_path${file_nm[x]}")
fi
done
