How to check for number of folders, then delete IF ...

Hello,

I have a daily backup script executing on my server. I would like to be able to delete the "last" backup. for ex the folder that's 30 days old.

Can someone help me find a command that will check for the oldest folder ? Then do an action with that folder. In this case, delete.

Thanks in advance for any help.

Code:

find ~ -type d -mtime +30 -exec rm -r {};

Find and delete every directory in your home directory that have not been modified in the last 30 days.

Code:

find ~ -type d -mtime +30 -print;

to print such directories

Hi
In my bash terminal, when I tried troop's command,
The last semicolon in "rm -r {} ;" command has to be escaped with \ (ie replace with "rm -r {} \;" )

Thanks for the replies. How can I just -print the directories and not what's inside them. The above command was looking for directories 30 days old inside my parent directories. I know this might sound confusing.

ex:
/MainDir
Dir1
Dir2
Dir3

If im in "MainDir", I only want to print "Dir1", not the directories that are inside it.

Thanks.

Solved with -maxdepth 1 option.

Thanks.
