  • How do I get root permission in Kali Linux?

    The root user name or account has default permission to all available commands and files on a Linux or any other Unix-like operating system. It is also known as the superuser, the root account, and the root user. Username: “kali” are the standard credentials for logging into the new Kali system. This establishes a session as user “kali,” You must use this user password after “Sudo” to gain root access. Kali Linux was using the root account by default till recent times. Root login is restricted in the current versions of Kali, allowing you to utilize your regular user account to access the GUI. The reasons behind this modification should be clear, but if you are a Kali user, you are presumably already familiar with a Linux system; thus, there is a little risk in allowing you to log in with the root account. We will create a non-root user with administrative capabilities while we install Kali Linux. Other Linux distributions follow a similar procedure. The default user in older versions of Kali is root. But first, we must create a regular account before installing Kali Linux. To install any program or package under Kali, we must first log in and then use the Sudo command.

  • How Do I Enable And Disable GPU Acceleration In Google Chrome?

    Google chrome comes equipped with many quality features that help sustain your PC health and perform tasks more efficiently. Since Chrome uses a huge amount of CPU, it has the feature of hardware acceleration that shifts the process to other hardware components, such as the GPU, to accelerate the job. Hardware acceleration was not so common in the initial days as the processor was responsible for handling all such jobs. Due to the latest trends and updates in web apps, the graph of requirements has potentially raised. In this article, we will be discussing GPU acceleration in Chrome. Make sure you read till the end.

  • su vs. su –

    The difference between the su and the hyphenated su – commands is the su command without arguments keeps almost all environment variables belonging to the original user. Contrary to this, the hyphenated su – command clears most environment variables.

    We are not talking about two different commands but about a command without a specific flag (the hyphen is a flag) and the same command with the flag.

    Typing su – is the same as typing su -l; both commands will clear most of the environment variables. Thus, before continuing with this article, let’s see what an environment variable is.

  • What Does =~ Mean In Bash?

    A Bash program is a simple text document with a series of instructions in it. These statements combine instructions we’d put on the command prompt manually (including such ls or cp). Likewise, whatever you can accomplish with a script could also be done with a command prompt. A regular expression matching sign, the =~ operator, is used to identify regular expressions. Perl has a similar operator for regular expression corresponding, which stimulated this operator. Let’s have some examples to see the working of =~ operator in Ubuntu 20.04.

  • Use of `shift` command in bash

    When the command-line arguments take inputs from the user, the first argument contains the script name. Sometimes the script name is required to omit for programming purposes. This task can be done easily by using any loop in bash. Using the `shift` command is another way to do the task. This command is used to move one positional parameter to the left by default. The different uses of the `shift` command in bash have shown in this tutorial.

  • Use of optional argument and default value in bash function

    A function is an essential part of any programming language that contains a block of code.

A function can be defined without argument and with argument. The argument of the function can be mandatory and optional. The default value can be set for the argument of the bash function. The ways to declare the optional argument and the use of default values in the bash function have shown in this tutorial.

The special variable that we will be discussing in this article is “$_” which is there to print the last argument of the previous command. It is a bit complex to understand the functionality of this special variable without looking at relevant examples. Therefore, we have designed this tutorial so that it will first explain to you the use case of this command, followed by a relevant example. Let us find out together what this article holds for us.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
