VIM tutorial for beginners

  • linuxconfig.org; By Luke Reynolds (Posted by linuxer on Nov 21, 2022 4:50 PM EDT)
  • Story Type: Tutorial, Video; Groups: Linux
The Vim editor (and its predecessor, vi) is a command line editor for Linux systems. It has a long standing reputation as being the most powerful text editor on Linux. After mastering it, many users will even claim that it is far speedier and more convenient to use than a typical GUI editor packed with lots of features in its menus.

Vim has a staggering number of features and functions, but they are all hidden behind keyboard shortcuts and commands. There are no menus or hints in Vim, as users are expected to have enough of a grasp to navigate around on their own. And this is where Vim’s learning curve turns off most new users from bothering with it. Many novices would rather stick with something simple, like nano, than deal with all Vim’s depth.

Bash Scripting Cheat Sheet

The ability to automate tasks with Bash scripts in Linux is one of the operating system’s most powerful components. However, due to the sheer amount of scripting components, it can be intimidating for newcomers. Even longtime users may forget something every once in a while and that is why we have created this Bash scripting cheat sheet.

Bash Script: Flags usage with arguments examples

If you have any experience on the Linux command line, then you should have run into command flags, which help us modify the behavior of a command that we are executing.For example, if we execute the ls -l command, the -l part of the command is a flag that we are passing as an argument to ls. This same functionality can be used in a Bash script, allowing us to pass some input to the script through flags when we are executing the script.

Bash script: Pause script before proceeding

Normally, a Bash script will execute each line of code the moment it reaches it, then immediately move on to the next. But it is also possible to add pauses to a Bash script in order to delay it or allow the user time to respond to a prompt, etc.

  • Story Type: Tutorial; Groups: Linux
Qcow2 is the default virtual disk storage format used by Qemu (qcow stands for qemu copy-on-write). This image format makes use of thin provisioning, so, after we initially set the maximum virtual size of a disk, space is actually allocated only when used, but not made available back to the host when freed.In this article we see how to “sparsify” a qcow2 disk image to reclaim available space, how to expand it or shrink it, and how to manage the partitions layout on it from the host system, connecting it by using the NBD protocol.
