While working on projects, I 've compiled a small number of tips and walkthroughs that I 've documented here.

Walkthroughs for small tasks in Linux

Give a user sudo access

When I first set up Ubuntu on my PC and ran it, I was annoyed to find that no, my default user did not have sudo privileges. It took me way too long to find out how to do such a small task, so here 's a straightforward walkthrough:
----
How to add a user to the sudoers file
----
The sudoers file is a configuration file on Unix-like systems (including Linux and Mac) that controls and defines user permissions for executing commands as another user (typically the superuser) using the sudo command. It is typically located at /etc/sudoers and should be edited with the visudo command to prevent syntax errors.
----
Note that you need root access for this. For which you will need to log in to a user account who already has root access. A fresh installation of Ubuntu 24.04 will have a root user account that you can use for this. Login using the password root .
----
Once you 're logged in as a root user, enter the command
visudo
You might need to use
sudo visudo
For this example, If I 'm trying to give user leahtara sudo privileges, so I 'll scroll to the bottom and add the following line of code to the file:
leahtara ALL=(ALL:ALL) ALL
Simply replace leahtara with your username of choice.
----

customise the terminal

I 'm going to be blunt here. The default graphical user interface for Ubuntu 's terminal is just plain ugly. So let 's fix that!
----
Here, I 've outlined a few basic steps that you can use to make your terminal pretty in just a few minutes.
----
We 're going to use Starship, an open-source, cross-shell prompt that makes it easy to customize and configure the Linux terminal prompt if you care about the looks of your terminal.
----
Setting up Starship
----
First we install Starship:
sudo snap install starship
We need to ensure that we 're in the home directory before we try to enable it.
cd ~
Now to enable it let 's edit the .bashrc file using
nano .bashrc
The last step is to add this line to the end of the file:
eval "$(starship init bash "
And there you have it! Your very own pretty terminal!

Clone a specific directory from inside a github repository

Sometimes your PC just doesn 't have enough storage left to clone that entire Tryhackme dump repo and you just need one of those directories at a time.
Follow along to learn how to do just that.
----
Clone the Repository
----
First we 're going to clone the Repository with No Content:
git clone --no-checkout <repository_url >
cd <repository_name >
git sparse-checkout init --cone
Don 't forget to insert the correct url which you can get from the repository 's page from github.com .
----
Pull your directory
----
Specify the Sub directory You Want:
git sparse-checkout set <subdirectory_path >
You can copy the subdirectory path also from the github repository page once again.
Now just pull the files using:
git checkout
