find 是此类任务的常用工具:

find is the common tool for this kind of task :

find ./my_dir -mtime +10 -type f -delete

说明

• ./my_dir 您的目录(替换为您自己的)
• -mtime +10 超过 10 天
• -type f 仅文件
• -delete 并不奇怪.在执行整个命令之前删除它以测试您的 find 过滤器

• ./my_dir your directory (replace with your own)
• -mtime +10 older than 10 days
• -type f only files
• -delete no surprise. Remove it to test your find filter before executing the whole command

并注意 ./my_dir 的存在以避免意外！

And take care that ./my_dir exists to avoid bad surprises !
