Time command

The `time` command is a tool used in programming and system management to measure how much time a specific process or program takes to run. When you use `time`, it shows you detailed information about the duration, such as how long the process took in real-world seconds, as well as the time spent by the CPU executing the process. This helps developers and system administrators analyze the performance of programs, optimize code, and understand how long tasks require to complete, making it a valuable tool for efficiency and resource management.
