删除文件使用shell脚本在Unix中早于10天
问题描述:
我是新来的shell脚本,谁能帮助?我想从当前日期的文件夹中删除脚本回10天。
这些脚本如下:
I'm new to shell scripts, can anyone help? I want to delete scripts in a folder from the current date back to 10 days. The scripts looks like:
2012.11.21.09_33_52.script
2012.11.21.09_33_56.script
2012.11.21.09_33_59.script
该脚本将每10一天运行crontab,这就是为什么我需要的当前日期。
The script will run in every 10 day with Crontab, that's why I need the current date.
答
找到
是这类任务的常用工具:
find
is the common tool for this kind of task :
find ./my_dir/* -mtime +10 -type f -delete
说明
-
./ MY_DIR
目录(用自己的替换) -
-mtime +10
早于10天 -
型的F
仅文件 -
-delete
毫不奇怪。删除前测试
-
./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 before
和照顾的 ./ MY_DIR
的存在是为了避免不良的惊喜!
And take care that ./my_dir
exists to avoid bad surprises !
