Being able to create and edit text files in Red Hat Enterprise Linux (RHEL) 8 is a simple yet important task.
In these examples we will cover the Red Hat Certified System Administrator (RHCSA) objective “Create and edit text files”, both through the graphical user interface and command line.
In these examples we will cover the Red Hat Certified System Administrator (RHCSA) objective “Create, delete, copy, and move files and directories”.
Within Linux, links allow us to refer to a target file using a different source – the link. When the link is accessed, we’re redirected to the defined target.
In these examples we will cover the Red Hat Certified System Administrator (RHCSA) objective “Create hard and soft links”.
The true power of Linux rests in the command line interface. If you are a Linux administrator, power user, or just like to tinker with your machine, you will be spending time in the Linux terminal. In today’s modern Linux operating system, most of us will actually use a terminal emulator. A terminal emulator is just a graphical application designed to run in the graphical user interface that accesses and emulates the command line interface found on all Linux installations.
There are many different terminal emulators out there, some come standard with different distributions while others you have to install yourself. Today, we will examine five of the best terminal emulators for Linux so you can discover the best terminal emulator for your needs.
The Socket Statistics (ss) command is similar to netstat, in that it is used to display useful network socket information.
For some time now the netstat manual page has noted “This program is obsolete. Replacement for netstat is ss.”, so this is going to be a useful command to know how to use moving forward.
Fortunately a lot of the options are similar to the ones used by netstat, however there are a few differences as we will see.
If you’ve accidentally deleted a file in Linux, don’t worry, you can probably still restore it as long as that area of disk has not yet been overwritten. This post will show you how to easily restore a deleted file in Linux.
Foremost is able to search a disk or raw image file to recover files based on their headers, footers, and internal data structures.
In order to prevent a file or directory from being accidentally or intentionally modified, renamed or deleted in Linux, we can set the immutable flag which will disable this functionality.
This post will show you how to check which version of Linux Mint you are running. This can be done both through the graphical user interface or command line, we’ll cover both options here.
By default a full installation of Debian 9 Linux will have the graphical user interface (GUI) installed and it will load up after system boot, however if we have installed Debian without the GUI we can always install it later, or otherwise change it to one that is preferred.
This quick guide will cover how to install LXDE on Debian 9 Stretch, which will provide a GUI for working with the Linux system. While I don’t suggest using a GUI on a production server, it’s a good option if you’re using Debian as a desktop.
