Understanding User Permissions in Ubuntu

User permissions in Ubuntu play a crucial role in managing system security and access control. Ubuntu, like other Linux distributions, follows a multi-user architecture where each user has specific rights and restrictions based on their role. Understanding these permissions helps in effectively managing user access, securing files, and executing administrative tasks.

Types of Users in Ubuntu

1. Root User – The superuser with full control over the system.
2. Regular Users – Have limited access and require permission to execute administrative commands.
3. System Users – Created for system processes and services.

User Permissions in Ubuntu

Every file and directory in Ubuntu has three types of permissions:

• Read (r) – Allows viewing the content of a file.
• Write (w) – Allows modifying a file or directory.
• Execute (x) – Grants permission to run a file as a program or script.

Permissions are assigned to three categories:

1. Owner – The user who created the file.
2. Group – A set of users with shared access.
3. Others – All other users on the system.

Managing User Permissions

• To change users in Linux, use the su command to switch to another user.
• The sudo command allows temporary administrative access for authorized users.
• To switch users in Linux, use su – username in the terminal.

To create new users, use the adduser command:
bash
CopyEdit
sudo adduser new_username

By understanding and managing user permissions, you can maintain a secure and efficient Ubuntu system.linux change user 

Root vs. Standard vs. Guest Users: An Ubuntu Comparison

Ubuntu, like other Linux distributions, follows a multi-user environment where different user types have varying levels of control and access. Understanding the differences between Root, Standard, and Guest users helps in managing system security and permissions effectively.

1. Root User (Superuser)

The root user is the most powerful account in Ubuntu with unrestricted access to all system files and settings. It can install and remove software, modify system files, and manage user accounts. However, direct login as root is disabled by default in Ubuntu linux change user security reasons. Instead, users can gain root privileges using the sudo command.

Example:

bash

CopyEdit

sudo su

This command allows you to switch to the root user temporarily.

2. Standard User

A standard user has limited access, mainly restricted to their own files and directories. They cannot modify system settings or install software without sudo privileges. However, they can perform everyday tasks like browsing the web, editing documents, and running applications.

To switch users in Linux, use:

bash

CopyEdit

su – username

3. Guest User

A guest user has even more restrictions than a standard user. They can log in without a password but cannot install software, modify system files, or access other users’ data. Their session is temporary, meaning all changes are lost after logout.

Managing Users in Ubuntu

• To change users in Linux, use the su command.

To add a user in Linux Ubuntu, run:
bash
CopyEdit
sudo adduser new_username

The Role of Permissions in User Switching in Ubuntu

User permissions play a crucial role in managing access and ensuring security when switching between accounts in Ubuntu. Whether using the Graphical User Interface (GUI) or Command Line Interface (CLI), permissions determine what actions a user can perform and whether they can successfully switch users in Linux.

1. Understanding User Permissions

Each user in Ubuntu has specific permissions that define their level of access:

• Standard Users – Have limited access and cannot modify system settings.
• Administrators (Sudo Users) – Can execute commands with elevated privileges.
• Root User (Superuser) – Has full control over the system.

Files and directories in Ubuntu also have Read (r), Write (w), and Execute (x) permissions, assigned to:

1. Owner – The user who owns the file.
2. Group – Other users in the same group.
3. Others – All other users.

2. How Permissions Affect User Switching

A standard user cannot switch to another user unless they know the target user’s password:
bash
CopyEdit
su – username

Sudo users can switch to other accounts or the root user with:
bash
CopyEdit
sudo su

• If permissions restrict access, users may receive a “Permission Denied” error when attempting to change users in Linux.

3. Assigning Permissions to New Users

When you add a user in Linux Ubuntu, you can grant administrative rights by adding them to the sudo group:

bash

CopyEdit

sudo usermod -aG sudo new_username

Changing User via Command Line Interface (CLI) in Ubuntu

In Ubuntu, switching between user accounts via the Command Line Interface (CLI) is an essential skill for system administrators and regular users. The terminal provides linux change user  efficient ways to switch users, execute commands with different privileges, and manage multiple user accounts.

1. Switching Users with the su Command

The su (substitute user) command allows you to switch users in Linux without logging out.

Syntax:

bash

CopyEdit

su – username

Example:

bash

CopyEdit

su – john

This command switches to the user “john” and loads their environment. You need to enter the user’s password.

To switch to the root user (if permitted):

bash

CopyEdit

sudo su

2. Using sudo for Temporary User Privileges

Instead of switching users entirely, you can execute commands as another user using sudo.

Example:

bash

CopyEdit

sudo -u username command

This runs a command as another user without a full switch.

3. Adding a New User Before Switching

If you need to create a new user before switching, use the adduser command:

bash

CopyEdit

sudo adduser new_username

After creating the user, you can switch to them using su – new_username.

Switching Users through Graphical User Interface (GUI) in Ubuntu

Ubuntu provides a user-friendly Graphical User Interface (GUI) to switch between multiple user accounts seamlessly. This method is ideal for users who prefer a visual approach over the Command Line Interface (CLI).

This is especially useful for shared computers, linux change user where different users need to access their accounts without disrupting each other’s work.

1. How Fast User Switching Works

Unlike logging out, which closes all running applications, Fast User Switching lets another user log in while keeping the previous user’s session active in the background. This way, each user can continue their work from where they left off after switching back.

2. How to Use Fast User Switching in Ubuntu (GUI Method)

1. Click the top-right system menu (near the power icon).
2. Select “Switch User” instead of logging out.

To use Fast User Switching effectively, each person must have their own account. You can add a new user in Linux Ubuntu using:

bash

CopyEdit

sudo adduser new_username

Creating a New User in Ubuntu

Each file and directory in Ubuntu has three types of permissions:

• Read (r) – Allows viewing the content of a file or directory.
• Write (w) – Grants permission to modify files or directories.
• Execute (x) – Required to run scripts or access directories.

Permissions are assigned to three groups:

1. Owner – The user who created the file.
2. Group – Other users in the same user group.
3. Others – All other users on the system.

2. Assigning Permissions Using the Command Line

After creating a new user, you can modify their permissions using the chmod and chown commands.

Change file ownership:
bash
CopyEdit
sudo chown new_username:file_owner filename

Modify permissions (Example: Full access to owner, read/execute for others):
bash
CopyEdit
sudo chmod 755 filename

To allow multiple users to share permissions, add them to a group:

bash

CopyEdit

sudo usermod -aG groupname new_username

4. Switching Users to Test Permissions

Once permissions are set, you can switch users in Linux to verify access:

bash

CopyEdit

su – new_username
