Logical Volume Manager (LVM) is used on Linux to manage hard drives and other storage devices. As the name implies, it can sort raw storage into logical volumes, making it easy to configure and use.

How to manipulate Excel spreadsheets with Python and openpyxl
Python is a general purpose programming language that needs no presentations. It was originally written by Guido Van Rossum, and saw its first release in the year 1991. At the moment of writing, the latest stable version of the language is 3.10. In this tutorial we see how to use it together with the openpyxl library to manipulate Excel spreadsheets.
Disable automount on Ubuntu
If you frequently use USB sticks or other USB storage devices, it may become annoying that they are automatically mounted whenever you insert them into your Ubuntu Linux system. This is especially the case with multi-partitioned USB drives.
Find setuid binaries to perform Linux server hardening
The purpose of this tutorial is to find setuid binaries on Linux. It is very possible that your Linux server has more packages installed than you really need. To make it worse, those extra packages may contain a handful of binaries with setuid and setguid turned on.
Convert ext3 to ext4 in Linux
The ext4 filesystem includes multiple improvements in terms of performance, over its predecessor ext3. Ext4 is not only faster than ext3, but can also handle much larger filesystems and files, and lots of other improvements under the hood. If you haven’t yet upgraded to ext4 on Linux, it’s definitely time to do so.
How to tune Linux extended (ext) filesystems using dumpe2fs and tune2fs
The ext2, ext3 and ext4 filesystems are some of the most known and used filesystems specifically designed for Linux. The first one, ext2 (second extended filesystems) is, as its name suggests, the older of the three. It has no journal feature, which is the biggest advantage of its successor over him: ext3. Released in 2008, ext4 is the more recent, and currently the default filesystem on many Linux distributions.
mount command in Linux with examples
We can use the mount command in Linux to attach file systems and removable devices such as USB flash drives. The default file system for most Linux distributions is ext4. We can also dismount file systems with the unmount command.
Megatools Linux install and Basic Introduction
This tutorial will deal with Megatools Linux install and Basic Introduction. MEGA is one of the most famous cloud storage and file hosting services available. The service offered by the company are normally accessible via web interface or dedicated applications also on smartphone operating systems such as Android or iOS. In this article we see how to access the service from the command line via a free and open source set of tools written in Python: Megatools.
wipefs Linux command tutorial with examples
The wipefs Linux command utility can be used to erase various types of signatures from a device (partition tables, filesystem signatures, etc…). It is available in the repository of all the most used Linux distributions, and it is usually installed by default as part of of the util-linux package, which contains also other essentials utilities aimed at system maintenance, so we should never have to install it explicitly. In this tutorial we will see how to use wipefs to gather information about the existing signatures and how to erase them.
logrotate command in Linux with examples
In Linux, many applications and system services will store log files. These log files give a Linux administrator insight into how their system is performing, and are invaluable when troubleshooting issues. However, log files can get unwieldy very quickly. For example, if your web server software logs every visit to your website, and you get thousands of viewers per day, there will be way too much information to feasibly squeeze into one text file.
