In Unix/Linux systems, which command is used to check

Solution

The top command in Unix/Linux provides a real-time, dynamic view of system performance, including CPU and memory usage, running processes, and load averages. It is a powerful tool for monitoring system health and diagnosing performance issues, particularly when trying to determine if the system is running out of memory or CPU resources. Understanding such commands is crucial for managing and maintaining Unix/Linux environments effectively. Why other options are wrong: b) ls : This command lists directory contents but doesn’t provide memory usage information. c) grep : This is a search command for filtering text, not for monitoring memory. d) chmod : This command changes file permissions and has no relation to memory usage. e) mv : This command is used to move or rename files, not to monitor memory.
