If you want to perform a benchmark test on a USB thumb drive or other external USB hard drive, the procedure is quite similar to doing a benchmark test on an ordinary, internal storage device. All that we need to do is measure the read and write speed of the USB drive. In this tutorial, you will see how to benchmark test a USB drive via command line and GUI on a Linux system.
In this tutorial you will learn how to create a bootable Microsoft Windows USB. This will allow you to install Microsoft Windows on another computer. Two methods of bootable Windows USB creation will be shown, depending on if you want to create it via GUI or command line. You can be using any GNU/Linux distribution to follow along with us below.
Video metadata contains information like author, title, genre, comment, and creation date. This information is embedded in the video file itself, but it not really a common practice for video releases to contain a lot of metadata info. If nothing else, there is usually some copyright information. In this tutorial, you will see how to get and change video metadata on a Linux system. This can be accomplished from both command line and GUI. We will cover both methods below.
In this tutorial, you will learn where to download and how to download Ubuntu 20.04 LTS ISO image for Ubuntu, Kubuntu, Ubuntu Budgie, Ubuntu Studio, Xubuntu, Lubuntu, Kylin desktops and Ubuntu 20.04 Server. Additionally, you can download server preinstalled images for Raspberry Pi and various other architectures. Lastly, hypervisor cloud images such as Azure, Vagrant, KVM or VirtualBox are also available for download.
Most of us longtime Linux users have the
ifconfig command seared into our brain, after years of repetitive use. It comes as a shock to some when they type the command and are met with an error message (ifconfig command not found). Indeed, the command has become deprecated, but it’s still possible to install ifconfig command.
It may be necessary to configure Linux IP forwarding on a Linux system in certain scenarios. If the Linux server is acting as a firewall, router, or NAT device, it will need to be capable of forwarding packets that are meant for other destinations (other than itself). Linux uses the net.ipv4.ip_forward kernel variable to toggle this setting on or off.
The purpose of this tutorial is to show various methods on how to remove or substitute spaces within a file name. Some tools on a Linux system may not work properly with files that contain spaces, which would give some users motivation to replace the white space with underscores or just delete them completely, for example. Manipulating files without white space is much easier, as you do not have to worry about escaping the file name each time. In this tutorial, you will see how to remove or substitute the spaces in file names in Linux.
You have two options when configuring the IP address on your Ubuntu Server, and that is either a static IP address or DHCP. A static IP address allows you to manually select your IP address by configuring it on the Linux system, whereas DHCP relies on the router or DHCP server to lease you an IP address – either a reserved one or the next available one that is currently free, depending on the setup.
When a script or process exits or is terminated by some other means, it will have an exit code, which gives some indication about how or why the script or process ended. For example, an exit code of
0 means that the process exited without error – in other words, it completed its task and exited as expected. On the other hand, an exit code of
1 means that the process encountered some kind of error upon exiting.
The locale on a Linux system is what determines the type of characters and encoding that appear in your command line terminal. Changing the locale will set various environment variables to different values. The terminal and other applications can then query those variables to figure out what type of characters and settings to show the user.
The system clock and the hardware clock are used for different purposes on a Linux system. The system clock is maintained by the operating system, and the hardware clock is maintained in BIOS. The hardware clock will continue to keep time when the computer is powered off, thanks to the CMOS battery on the motherboard. The system clock maintains time by querying online time servers whenever the computer is powered on.
