The htop command is used to launch a system monitoring utility in the Linux command-line interface. It provides a more interactive and visually appealing alternative to the traditional top command.

htop displays various information about the system's resources and processes in real-time. It has a user-friendly interface with color-coded columns and graphs. Here are some key features and functionalities of htop:

1. Process Listing: htop lists all the running processes on the system, including their process IDs (PIDs), CPU usage, memory usage, and the amount of time each process has been running.

2. Resource Monitoring: The utility shows real-time usage statistics for CPU, memory, swap memory, network traffic, and disk I/O.

3. Process Control: With htop, you can interact with individual processes. You can send various signals to a process for management, such as terminating or killing a process.

4. Sorting and Filtering: It allows you to sort processes by different criteria such as CPU usage, memory usage, process name, and more. You can also filter processes based on a specific string or criteria.

5. Interactive Interface: htop provides an interactive interface where you can navigate and scroll through the process list using keyboard shortcuts. It offers a more intuitive and dynamic view of system status compared to the static top command.

Overall, htop is a powerful command-line tool for monitoring system resources and processes in real-time, aiding in system troubleshooting, performance analysis, and process management.
