How to Change Your Username in Linux
Linux enables multiple users to access the same system at a time, or we can say it is a multi-user OS. Along with that, there are multiple responsibilities that the admin must manage like giving permissions to users, allotting unique id names, etc. When we talk about changing the credentials of users like changing their ids or name, Linux also enables us to change the name of the user using commands.
To change the username in the Linux operating system, we use a command called “usermod”. The “usermod” command is a command line utility or library which is provided by Linux that is used to change the properties that are related to the user information. Like other command line utilities, this utility also takes options as input to analyze what action to perform. In our case, what this command does is that it changes or modifies the root system files which are called system account files to make the changes that are specified in the command line prompt. One thing to keep in mind before performing such an activity is that we should not edit or modify the /etc/passwd file manually or by any text editor.

How to Check the CPU Temperature in Linux
Laptop overheating is one of the most heard complaints. As we know, the components in laptops are congested because of their thin body. Sometimes, it heats up and may cause damage to the internal parts of the laptop. For this reason, a regular checkup for the CPU temperature is necessary. Since the CPU is the central component of every desktop computer, monitoring the temperature of the CPU is extremely important. The device automatically shuts off if the CPU temperature rises to 90°C or above for a variety of causes that could impair the performance of the Linux kernel or even the apps. Even though the temperature does not reach that level, a temperature change can nonetheless damage any central processing unit. Monitoring the CPU temperature is a wise habit if you routinely work for extended periods on CPU-intensive tasks.

How Do You Grep Case Sensitive?

The “grep” command must be used with the “-i flag” when looking for a gradient. When users are unclear about the situation, they choose to ignore it.
