    Updating a File:

1. Create a new file named "autoupdate" under /etc/cron.daily/:

Use the vim text editor to create the file:
sudo vim /etc/cron.daily/autoupdate
Note: If you're not familiar with vim, you can use nano or any other text editor instead.
Save and exit the file.
2. Paste the script into the file:

Here's a script for OS Update with Dist-upgrade:
#!/bin/sh
{
    echo "Auto update started on $(date)"
    sudo apt-get update
    sudo apt-get upgrade -y
    sudo apt-get dist-upgrade -y
    sudo apt-get autoclean
    sudo apt-get autoremove -y
    echo "Auto update completed on $(date)"
} >> /var/log/autoupdate.log

mail -s "Auto update report for Server :Website_API_10.4.0.230 $(date)" -a "From: no-reply@domain.org" your_email@domain.org < /var/log/autoupdate.log
Or use this script for Dist-upgrade only:
#!/bin/sh
{
    echo "Auto update started on $(date)"
    sudo apt-get update
    sudo apt-get upgrade -y
    echo "Dist-upgrade started on $(date)"
    sudo apt-get dist-upgrade -y
    echo "Dist-upgrade completed on $(date)"
    sudo apt-get autoclean
    sudo apt-get autoremove -y
    echo "Auto update completed on $(date)"
} >> /var/log/autoupdate.log

mail -s "Auto update report for Server :Subject Name/Server Details $(date)" -a "From: no-reply@domain.org" your_email@domain.org < /var/log/autoupdate.log
Remember to replace your_email@domain.org with your actual email address.
3. Make the "autoupdate" file executable:

sudo chmod +x /etc/cron.daily/autoupdate
Save and exit the file.

smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes

Save and exit the file.
4. Edit the /etc/postfix/sasl_passwd file and add this line:

Don't forget to replace your_email@domain.org with your actual email address.

That's it! Remember to check the logs (/var/log/autoupdate.log and /var/log/clamscan.log) from time to time to ensure everything is running smoothly. Use cat /var/log/autoupdate.log and cat /var/log/clamscan.log to display these logs.
