You probably shouldn’t update your BIOS, but sometimes you need to. Here’s how to check what BIOS version your computer is using and flash that new BIOS version onto your motherboard as quickly and safely as possible. Be very careful when updating your motherboard’s BIOS! If your computer freezes, crashes, or loses power during the process, the BIOS or UEFI firmware may be corrupted.
[mai mult...]Directories on Linux let you group files in distinct, separate collections. The downside is it becomes tedious moving from directory to directory to perform a repetitive task. Here’s how to automate that.
The first command you learn when you’re introduced to Linux is probably ls, but cd won’t be far behind it. Understanding directories and how to move around them, particularly nested subdirectories, is a fundamental part of understanding how Linux organizes itself, and how you can organize your own work into files, directories, and subdirectories.
Grasping the concept of a tree of directories—and how to move between them—is one of the many little milestones you pass as you familiarize yourself with the landscape of Linux. Using cd with a path takes you to that directory. Shortcuts like cd ~ or cd on its own take you back to your home directory, and cd .. moves you up one level in the directory tree. Simple.
However, there isn’t an equally simple means of running a command in all directories of a directory tree. There are different ways we can achieve that functionality, but there isn’t a standard Linux command dedicated to that purpose.
Some commands, such as ls, have command-line options that force them to operate recursively, meaning they start in one directory and methodically work through the entire directory tree below that directory. For ls, it’s the -R (recursive) option.
If you need to use a command that doesn’t support recursion, you have to provide the recursive functionality yourself.

On Linux computers, system resources are shared amongst the users. Try to use more than your fair share and you’ll hit an upper limit. You might also bottleneck other users or processes.
