Cron Job to Delete Files Created Before a Specific Time

Cron job to delete files created before a specific time

If you're using GNU find, try this:

find /home/username/public_html/temp -type f -mmin +5 -delete

Should also work with FreeBSD or many other versions of find.

Cron Job to auto delete folder older than 7 days Linux

For example, the description of crontab for deleting files older than 7 days under the /path/to/backup/ every day at 4:02 AM is as follows.

02 4 * * * find /path/to/backup/* -mtime +7 -exec rm {} \;

Please make sure before executing rm whether targets are intended files. You can check the targets by specifying -ls as the argument of find.

find /path/to/backup/* -mtime +7 -ls

mtime means the last modification timestamp and the results of find may not be the expected file depending on the backup method.

How to delete folders that are older than a day? (Cron Job)

This should do it:

find /path/to/dir -maxdepth 0 -ctime +1 -exec rm -fr {} +

But be careful, and test it first outside of cron, without the -exec part, so you don't delete something else by accident.

Delete folder older than 30 minutes with Cron

I actually found out that the best method is to divide the commands in Cron in 2 parts, and use the -delete argument

Code

30 * * * * sudo find /my/folder/* -type f -mmin +30 -delete && sudo find /my/folder/* -type d -empty -mmin +30 -delete 

Explanations

30 * * * *: execute every 30mn all the time

sudo find /my/folder/* -type f -mmin +45 -delete : delete all files and subfiles that are older than 45 minutes

&& : do only if first command has successfully run

sudo find /my/folder/* -type d -empty -mmin +45 -delete : delete all empty folders that are older than 45 minutes

Working on Ubuntu 16.04

Auto delete files every one hour in ubuntu

Finally found a solution for delete files every one-hour using crontab.

First, write the shell script.

root@admin:/home/ubuntu#vi delete_cache.sh

after creating the file add the below scripts in delete_cache.sh

rm -rf /var/tmp/*

then run a crontab.

root@admin:/home/ubuntu# crontab -e   
0 * * * * /bin/sh /home/ubuntu/delete_cache.sh

The 0 at the beginning means to run at the 0th minute. the script would run every hour. for more see here, you can create your own cronjobs

How to delete files from directory on specific time, daily?

The script you posted deletes .txt files in the given folder if they are older than a day but the problem is that this test only happens once - when you run the script.

What you need to do is run this script periodically. If you are running this on Linux you should probably add a cron job that executes this script periodically, say once an hour or once daily.

If you're running this on Windows, there is a task schedule that you could use to accomplish the same thing.
