p7zip

Installation

Install the p7zip package.

The command to run the program is the following:

$ 7z

Examples

Warning: Do not use 7z format for backup purposes, because it does not save owner/group of files. See 7z(1) § Backup and limitations for more details.

Add file/directory to the archive (or create a new one):

$ 7z a archive_name file_name

Also it is possible to set password with flag -p and hide structure of the archive with flag -mhe=on:

$ 7z a archive_name file_name -p -mhe=on

Update existing files in the archive or add new ones:

$ 7z u archive_name file_name

List the content of an archive:

$ 7z l archive_name

Extract all files from an archive to the current directory without using directory names:

$ 7z e archive_name

Extract with full paths:

$ 7z x archive_name

Extract into a new directory:

$ 7z x -ofolder_name archive_name

Check integrity of the archive:

$ 7z t archive_name

Fixing update-grub command not found Error in Arch Linux

Why do you see 'update-grub' command not found error?

You see the error because update-grub is not a standard command like ls, cd etc. It's not even a standard command that is installed with grub.

In Ubuntu, the command is just an alias and when you run the update-grub command, it runs the following command instead:

sudo grub-mkconfig -o /boot/grub/grub.cfg

The grub-mkconfig is the command for managing grub. But the above command is difficult to remember so the aliased shortcut update-grub was created.

📋
You can either run the above grub-mkconfig command or create a custom update-grub command to run the same.

How to fix the update-grub command not found error

You can put some effort and create a custom update-grub command the same way it is implemented on Ubuntu and Debian.

It is a four-step process and I will assist you with every step.

Step 1: Create a new file

To create the update-grub command, the first step is to create a new file.

So open your terminal and use the following command:

sudo nano /usr/sbin/update-grub

What the above command will do is create a new file named update-grub in the /usr/sbin/ directory.

If you notice, there's a nano command used which is a text editor which is responsible for creating an opening the file just after executing the command.

It will open an empty file looking like this:

create new file to solve update-grub command not found error

Step 2: Write new lines to the file

(secret: you don't have to write but paste those lines 😉)

Once you execute the previous command, it will open the file where you have to add lines.

Simply select the following lines and paste them into the terminal using Ctrl + Shift + V:

#!/bin/sh 
set -e 
exec grub-mkconfig -o /boot/grub/grub.cfg "$@"
file contents to create a new file

Now, save changes and exit from the nano editor using Ctrl + O, press the Enter key and then Ctrl + X.

Step 3: Change ownership of the file

Once you are done creating the file, you have to assign the ownership to the root user of that file.

For that purpose, you'd have to use the chown command in the following manner:

sudo chown root:root /usr/sbin/update-grub
change file ownership in linux

Step 4: Change file permissions

In the last step, you have to change the read-write permissions using the chmod command as shown here:

sudo chmod 755 /usr/sbin/update-grub
change the read write permissions of the file

What the above command will do is only the file owner can read, write, and execute the file whereas others can only read and execute.

Once done, use the update-grub command it should work like you expect:

sudo update-grub
solved: sudo: update-grub: command not found error

What's next? How about customizing GRUB?

Well, there's a perception that everything related to GRUB is difficult but it is not and customize the GRUB bootloader as per your liking without any complex steps.

For that purpose, you'd have to install grub customizer, a GUI utility to customize grub easily.

Sounds interesting? Here's a detailed guide on how to install and use grub customizer on Linux:

Customize Grub to Get a Better Experience With Linux
Couple of Grub configuration tweaks to get better experience with multi-boot Linux system using Grub Customizer GUI tool.

I hope you will find this guide helpful.

Автоматичний вхід в Arch Linux (SDDM)

Налаштування автоматичного входу до системи SDDM

1. Перевірка наявності SDDM

Перед налаштуванням автоматичного входу SDDM необхідно переконатися, що він встановлений на комп'ютері. Для цього можна використати команду:

systemctl status sddm

Якщо SDDM не встановлений, його можна встановити командою:

sudo pacman -S sddm

2. Редагування конфігураційного файлу SDDM

В Arch Linux конфігураційний файл для SDDM розташований за замовчуванням /usr/lib/sddm/sddm.conf.d/default.conf. Цей файл можна відредагувати для налаштування SDDM, включаючи автоматичний вхід.

Відкрийте файл /usr/lib/sddm/sddm.conf.d/default.conf через термінал з правами адміністратора:

sudo vim /usr/lib/sddm/sddm.conf.d/default.conf

Додайте або відредагуйте наступні рядки, щоб увімкнути автоматичний вхід:

[Autologin]
User=username
Session=session_name.desktop

Замініть username на ім'я користувача та session_name.desktop на ім'я вашого графічного сеансу (наприклад, "plasma.desktop" або "i3").

Приклад:

[Autologin]
User=username
Session=i3
