UNIX for Dummies Questions & Answers

I have a system where i take hourly back-ups of the system.The script for maintaining full backup for the last 5 days is

Code:

find /backup/server -type f -mtime +4 -exec rm -f {} \;

works fine for keeping the files of some 5 days old.

In the case of hourly backups.How do we write to keep the files for 5 hours?i want only backups of the last five hours to be kept and the remaining should be deleted when the script runs. i am using the following naming procedure for the file to store.

Code:

backupXXXXX-$(date +%m-%d-%y.%H:%M:%S).tar.gz

can any one suggest me a solution?

instead of mtime use mmin

Eg:- -mmin 300 (exactly 5 hrs)

-mmin +300 (above 5 hrs)


HTH,
PL

i have contacted a friend who is a linux admin after i have posted the above post and guess what he too suggested the same solution and now the script is working just fine.
Thank you once again .
