User Management
User management in Linux is a crucial aspect of DevOps and system administration. Managing users and their permissions ensures that your systems are secure, organized, and meet the needs of your organization. Here’s an overview of user management in Linux within a DevOps context:
1 . Creating a User : To create a new user in Linux, you can use the useradd command. For example:
sudo useradd [usernam]
sudo useradd w3wiki
w3wiki user created
2. Setting a Password: After creating a user, set a password using the passwd command:
sudo passwd [username]
setting password for w3wiki user
3. Deleting a User: To delete a user, use the userdel command :
sudo userdel [username]
deleting user w3wiki
4. Switch to Another User: The su command allows you to switch to another user’s account by providing the username as an argument. To exit from the user’s account and return to your original session, you can simply type ‘exit’.
su [USER NAME]
Switch to user w3wiki
5. Rename the User: To change the username from the current name (oldname) to the new name (newname), use the following command.
sudo usermod -l [newname] [oldname]
chnage the user name from w3wiki to GFG
