Crafting a Shell Script to Send Emails
Now let’s explore the process of creating a shell script to send emails. We’ll break down the steps involved and provide a sample script for reference.
Step 1: Define Script Parameters
Begin by defining the necessary parameters for your script, such as the recipient email address, subject, and message body. You can either hardcode these values directly into the script or pass them as command-line arguments.
#!/bin/bash
# Recipient email addressrecipient=”recipient@example.com”
# Email subject
subject=”Automated Email Notification”
# Email message body
message=”Hello,
This is an automated notification sent via shell script.
Regards,
Your Name”
Step 2: Construct the Email Command
Next, construct the command to send the email using your MTA’s command-line interface. The exact command may vary depending on your MTA. Below is an example using the mail command, which is commonly available on Unix-like systems.
Before constructing the email command we have to install mail.
In Kali Linux, you can install the mailutils package to send emails via a script using the mail command. Here’s how you can install it:
sudo apt update
sudo apt install mailutils
Once mailutils is installed, you should be able to use the mail command to send emails from your script. If you encounter any issues or need further assistance, feel free to ask!
# Send email using the ‘mail’ command
echo “$message” | mail -s “$subject” “$recipient”
Step 3: Save and Execute the Script
Save your script with a meaningful name, such as send_email.sh, and make it executable using the chmod command.
chmod +x email.sh
You can then execute the script from the command line to send the email.
./email.sh
