See my need, I have a cron that runs every morning and creates a file.ddmmaaaa.backup on the Linux Kubuntu server, it happens that the hard drive fills up quickly since this backup file has 500MB on average, how to create a cron that deletes files a date earlier than a week from the current date?

I kept thinking about how to do this but I don’t know much about cron and how I could put variables in cron, maybe the solution is script, but rs, I’m also very layy in script.

The Exclude Script would be roughly

delete /folder/file*. backup

Where file* would be with earlier dates

    Exactly, cron is only a utility that performs scheduled tasks. Nothing is programmed in it beyond the periodicity of the tasks that must be performed.

  • Yes a php script since this server has an apache and php running :-)

You can use the command find to fetch the old files and then remove them.

find /path/to -type f -mtime +7 -print0 | xargs -0 rm --

This way, the command will list all files that were modified at least 7 days ago.

You can override the parameter -mtime for -atime or -ctime, which checks the date of the last time the file was accessed or changed, respectively.
