Write a bash script that will do the following: Using the command "sudo fail2ban-client status sshd", from the output, get the banned ip addresses and sort them into the file "banned_ips.txt" displaying 1 ip address per line.
Answer from chatgtp needs some work:
#!/bin/bash
# Get the banned IP addresses using the fail2ban-client command
banned_ips=$(sudo fail2ban-client status sshd | grep "Banned IP list" | awk '{print $NF}')
# Sort the banned IP addresses and store them in a file
echo "$banned_ips" | sort | uniq > banned_ips.txt
This however only shows last ip address

In this playbook, the apt module is used to update the package index and install patches on Debian-based systems, while the yum module is used for the same on Red Hat-based systems. The when statement is used to conditionally execute the correct module based on the value of ansible_os_family.
After the patches have been installed, the playbook checks if a reboot is required by running the ls /var/run/reboot-required command. If the command returns a zero exit code, indicating that a reboot is required, the reboot module is used to perform the reboot.
