Will such a command delete a folder older than a certain time?

Question

linux

There is such a script for DB backup.
That is, I store hourly backups in a directory named date.
The last command will delete files.
But as far as I understand correctly, it will not delete directories.
How to delete directories older than a certain time, taking into account that there are no files older than this very specific time?

Answer 1

You need to go to Google, search for "find search directories older than",
find the line with directories and add it to the script with the -delete key

Answer 2

find $dest -type d \( -name "*-1[^5]" -o -name "*-[023]?" \) -ctime +30 -exec rm -R {} \; 2>&1
find $dest -type d -name "*-*" -ctime +180 -exec rm -R {} \; 2>&1

Why -exec rm -R {} if find has a -delete option?

How can I make sure that directories older than a certain time are deleted, taking into account that there are no files older than this very specific time?

Search for directories - to do this, you can add the option to find to find only directories.
