  5. Mapfile Bash Linux Command

    The bash shell Mapfile command is often known as a reading array. The primary purpose is to read standard input lines and store them in an indexed array variable. Mapfile must also read from substitution (<<) rather than a pipe. In addition, as compared to a read loop, bash Mapfile is a much faster and more convenient solution. It returns 1 if the execution of the command gets successful and 0 in case it is not successful. If we don’t specify an array name, the bash Mapfile variable will be targeting the array variable by default. Thus, we have decided to cover some examples using the mapfile instruction on the bash.

  6. Resolve Issue: Bash Bad Substitution

    You may have received the Bad substitution syntax problem while developing Bash scripts. After browsing through forums, you may discover that you are not alone; other individuals are encountering the same mistake. It’s a typographical fault that happens when you run your Shell script, and it can happen for a variety of reasons. The wrong use of instruction substitution and erroneous characters appended to the program are two major reasons for this.

    Let’s see how we can make our shell script cause this error and how to resolve it. Get started with the new bash file created with Ubuntu’s “touch” query and open it within the “GNU Nano” editor.

  7. Resolve Issue: Bash Unary Operator Expected

    Errors have a diverse number of types and reasons when it comes to bash programming. One of those errors is the “unary operator expected” error in bash programming. When evaluating expressions in conditional declarations, you may run into the “unary operator expected” issue. The reasons for this error “bash unary operator expected” might be diverse. We’ll start by talking about what’s creating the problem. Following that, we’ll go over a couple of options for resolving this problem. Let’s get started with today’s article by creating a new bash file in Ubuntu 20.04 system. For this, we need to utilize the “touch” instruction within the shell terminal and name the file “unary.sh”.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
