The company has a monitoring system on-line that makes a lot of files every day, and then needs to delete files that are a few days old to ensure that the hard drive is not full of service disruption.

The statement is also very simple,

/home/monitoring/-mtime +-exec rm-rf {} \; 

-mtime-n +n by file change time to find files,-n refers to n days or less, +n refers to n days ago

The-exec:find command executes the shell command given by the parameter to the matching file. The corresponding command is in the form of ' command ' {} \;, note the space between {} and \;

And then add a line from the scheduled task to OK,

Specific find usage can baidu a bit
