Linux – Delete files created 5 mins or earlier in a folder

find /u1/database/prod/arch -type f -mtime +3 -exec rm {} \;

vi samefilename 
#!/bin/bash

find /u1/database/prod/arch -type f -mtime +3 -exec rm {} \;

The only 2 commands used are find and rm.

Find looks for files (-type f), this to exclude directories, that are older then 3 days (-mtime +3). All it finds is given to rm (-exec rm {} \; ).

You could also place the rm statement outside of find, which is supposed to be faster:

find /u1/database/prod/arch -type f -mtime +3 | xargs rm

The data=writeback mount option deserves to be tried, in order to prevent journaling of the file system. This should be done only during the deletion time, there is a risk however if the server is being shutdown or rebooted during the delete operation.

According to this page,

Some applications show very significant speed improvement when it is used. For example, speed improvements can be seen (...) when applications create and delete large volumes of small files.

The option is set either in fstab or during the mount operation, replacing data=ordered with data=writeback. The file system containing the files to be deleted has to be remounted.
