shell脚本删除时间名字文件夹

shell中可以是直接对比日期大小

[root@node5 test]# [ 2022-05-30 < 2022-06-08 ] && echo yes || echo no
yes
[root@node5 test]# [ 2022-05-30 < 2022-06-08 ] && echo yes || echo no
yes

所以脚本可以这样写：

[root@node5 test]# cat del_time_dir.sh
#!/bin/bash
set -e
time=$(date -d '10 days ago' +"%F")
for dir in `ls -rt /root/test/ | awk '{print $NF}'`;do
     if [ $dir < $time ];then
     	rm -rf /root/test/$dir
        echo "$dir has been deleted"
     fi
done
