In Linux, you can switch between users by using the user command. To switch to the root user, type:user rootTo switch to the user jane1 account, type:user jane1To switch to the user john2 account, type:user john2You can also use the sudo command to temporarily become a different user. For example, to become the user jane2 and access all of her files and programs, type:sudo su - Jane2If you want to permanently change your username or password, you can do so by following these steps:1. Log in as your new username. If you don't have a login name yet, enter your computer's IP address into a web search engine and look for a tutorial on how to set up an SSH server on that machine. Once you've logged in as your new username (for example, if your computer's IP address is 192.168.1.100), try entering this command at the terminal prompt:passwd 2. Enter your current password twice (once in each field).3. Press Enter/Return key once all fields have been filled in correctly.4. Type exit at the prompt when finished logging out of your old account and logging in with your new username and password5./etc/passwd6./etc/group7./etc/loginconfig8./sbin/init9su - Jane2 10chkpw -l 11exitNow that you're logged in as Jane2, try running these commands one after another (without any spaces between them):echo "This is my first line"
echo "This is my second line"
exitThese commands will print their output on two separate lines because they are run from different accounts—in this case Jane2's account and root's account respectively.—but they would both print on one line if run from either of those accounts directly instead of through an intermediary like sudo or chkpw . If everything looks good after trying these commands out for yourself, congratulations! You now know how to use basic Linux commands.— Source :
How do you change your current user in Linux?

How do you change a username in linux?
There are three ways that you can change a username in Linux: using the su command, using sudo , or using fuser . Let's take a look at each one of them in more detail.
Using the su Command
The first way is to use the su command. To do this, first log into your system as root (using either the sudo or apt-get install root access commands if necessary). Then enter this line into terminal window:su – This will switch you into another user account called "root". You will then be prompted for that other user's password. Once you have entered it correctly, press Enter to continue and remain in that mode of operation (i.e., as root).
Using sudo Command
The second way is to use sudo . To do this, first log into your system as root (using either of those aforementioned commands), and then enter this line into terminal window:sudo – This will allow you access privileges similar to those of another administrator named "username". After entering their login credentials (which may include their name plus an @ symbol followed by their email address), they'll be asked whether they want to enable Super User Mode on behalf of all users on this computer; by default they should answer yes unless they specifically disable Super User Mode via a setting within /etc/sudoers . If so desired they can also set up time limits for when Super User Mode can be activated again by typing duration at once time limit : e . g . 10 minutes The next thing that happens is that any files owned by "username" which are located within directories which have been given permission 444 (read only) will automatically be copied over so that anyone who tries accessing them while "username" has Super User Mode enabled won't even see a prompt asking for their login credentials; after copying these files over it returns control back overto regular "root".

How to log into another user account in Linux?
In Linux, you can switch user accounts by using the following command:sudo usermod -a -G sudo your_new_userName
This will create a new user account called "your_new_userName" with permissions to access all files and folders in the current directory as well as any other directories you may be logged into.
How can I become root user in Linux?
In Linux, there are two types of users: normal users and root users. Normal users can only do what the user administrator allows them to do. Root users have all the privileges of a normal user plus they can make changes to the system that other users cannot.
To become root user in Linux, you first need to be a regular user and then use the su command to become superuser. The su command is short for "switch user." To use it, type su at the prompt and supply your username as an argument. Then, type your password when prompted. After you're logged in as root, you can use the following commands to change your status:
If you want to return to being a regular user again, just type exit at the prompt and you'll be back where you started. Remember that if something goes wrong while you're using root privileges, don't panic—just use the standard recovery procedures for your operating system.
How do I check who is logged in as which user in Linux?

Is it possible to login as two different users at the same time in Linux?
In Linux, it is possible to login as two different users at the same time. To do this, you first need to create a user account for each person you want to use. Then, when you log in, you will need to switch to the appropriate user account. Here are instructions on how to do this:
- Open a terminal window and type the following command: sudo adduser username new_user

- Type the following command to confirm that your changes have been saved: sudo yes
- Now log out of your current user account by typing exit followed by your username on one line and press enter on another line.
- Log in as new_user by entering their password and pressing enter.
