  • How To Change File & Folder Permissions on Linux Using Chmod

    When working with some files or folders on Linux you might have seen an error saying Permission Denied.

    This is a common error that is associated with the permissions for the specific file/folder.

    In this tutorial, you will learn different ways to change the file and folder permissions for any users or groups on Linux.

    Linux is an operating system that supports multiple users working on the same system. Thus, it is essential to manage the permissions such as who can see or modify the files and folders for every one of them.

    Although permissions and their notations may seem confusing at first, they make sense and are easy to understand once you get the basics. Also, please note that permissions can only be changed by the owner of the file or the system administrator known as root in Linux.

  • Using gLabels: An Update

    It came to my attention recently that since I wrote my previous article on gLabels, it's been nearly 9 years! While I did mention several features of gLabels, my favorite label program, I didn't do an actual tutorial or even review of the program. However, I did another one earlier. This one1s the how-to, but it1s been over 9 years since I wrote that.

    I recently had to do some labels at work (using my Windows 10 laptop) and found myself wishing I had gLabels with me in the town where my meeting was. It would have been MUCH simpler.

    gLabels is my absolute go-to for labels. It is in the PCLinuxOS repo and has been for as long as I can remember (it1s been a while since I registered on the forum in 2006). The current version is 3.4.1. Let me refresh your memory. I'm sure many of you already know this, but I'm going to try to cover details anyway.

    When you open the gLabels window, it's pretty blank, until you choose the label you want to use.

  • 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.
