    To send the output of your shell script to your email address, you can use the mail command in your script to send an email containing the status of the backup. Here’s a general outline of how you could achieve this:

    1. Configure Email Services:
      Before you begin, make sure your CentOS 7 VM is configured to send emails. You’ll need an email server or relay configured in your system for this to work.

    2. Modify Your Shell Script:
      Within your existing shell script that checks the backup status, you can capture the output of the script using command substitution and then send it via email using the mail command.

      #!/bin/bash

# Your existing backup check commands
backup_status=$(your_backup_check_commands_here)

# Send an email with the backup status
echo "$backup_status" | mail -s "Daily Backup Status" [email protected]

      Replace your_backup_check_commands_here with the actual commands that check the backup status. Also, replace [email protected] with your actual email address.

    3. Make the Script Executable:
      Ensure your script is executable by running:

      chmod +x your_script.sh

    4. Schedule the Script:
      You can use the cron scheduler to run your script at a specific time each day. Edit the crontab using crontab -e and add an entry like this to run your script, for example, every day at 10:00 AM:

      0 10 * * * /path/to/your_script.sh
