How to install Thunderbird on Debian 11 Bullseye - Linux Shout
Thunderbird is Mozilla’s developed open-source email client available for Windows, macOS, Linux, and other popular operating systems. The secure and free e-mail client “Mozilla Thunderbird” supports all common e-mail accounts, can encrypt outgoing messages on request, offers an integrated RSS reader, and is highly expandable. If you want, you can even use Thunderbird as a Twitter client.
The Mozilla e-mail client is easy to use and offers a tabs view, so you can, for example, cleanly separate emails from chats. By clicking “Compose” you can write new emails and add appointments and addresses optionally. For large mail stocks, there are practical tools for a better overview. So you can highlight important messages, hide read ones, or sort the mail into different folders. Very cool are the virtual folders, where you can automatically sort mails with certain criteria.

Uncover: Quickly Discover Exposed Hosts on the Internet from Linux - TREND OCEANS
Recently, I’ve written a detailed guide on the Smap alternative to Nmap that takes advantage of the Shodan API to generate identical output like Nmap, except it also fetches open port data from Shodan as an add-on to standard Nmap.
No doubt, Shodan is an amazing way to find devices connected to the internet. However, it is not the only search engine. There are several platforms like Censys and Fofa that offer you the chance to check if the device is connected to the internet.
If you have a list of IP addresses and check it on Shodan (to know whether they are exposed to the internet), in a very rare situation, you might not see any result declaring that they are not exposed. You leave that situation for further investigation. However, it is recommended to check IP addresses on multiple platforms to verify that they are 100% not exposed to the internet from anywhere.
To achieve this, you can take the help of various tools that help you perform all search engine searches from one tool without letting you manually visit each search engine for testing.
Of all those tools, one is the Uncover tool, which can give you the power to perform tests on hosts to check whether they are exposed to the internet.

Subfinder: Fast Passive Subdomain Enumeration Tool in Linux - TREND OCEANS
Today, most of the vulnerability or exploitation is done over the subdomains of a website where developers have less interest, which gives an attacker an open invitation to exploit their main website.
In some cases, the developer doesn’t even know which subdomain was created. From a security point of view, if you are doing security research, then it is your responsibility to know how to get a list of subdomains of the root domain.
Now, there are multiple ways to find a subdomain. For example, if you are a site admin and have access to a DNS record, then you can easily view the list of registered subdomains. In case you are not a site admin and just a security researcher looking for a subdomain of the root site to check a security flaw, then you should take the help of the subfinder tool.

How to View Saved WiFi Password in Linux Mint
A simple guide to view saved WiFi password in Linux Mint (all versions – Cinnamon desktop) for beginner’s.
If you use wireless connections and frequently connect to a list of WiFi access points, then you tend to save the password for seamless connectivity in Ubuntu and other systems. However, you may forget the password after a certain period. Here’s how you can quickly find it out.

Of course, it should be obvious to you that doing a fresh install of Ubuntu using the latest canary build is the only real way to “test” the revamped Flutter-built installer (y’know, to see if it actually installs anything). But not everyone wants to download a 4GB .ISO, create a USB, or go through the hassle of that.
Some folks (hi) just want to get a feel for the “experience” the new installer offers. Y’know, gawp at the visual changes between this subiquity-based creation and the GTK Ubiquity installer most of us are (intimately) familiar with, i.e. click through the steps to see how it compares.

We have covered all of Bash, except for Functions. Functions can be very helpful for a script.
If you have any programming experience, then you should already have an understanding of the Function. A Function is a set of commands that you utilize multiple times. We can set the Function up one time and called as many times as we need.
