nproc

nproc is a command line tool that is used to fetch the number of processing units available on a system. Here are some key points about this tool:

1. The name "nproc" stands for "number of processors".
2. It is mainly used in Unix-based operating systems, such as Linux.
3. The tool provides information about the total number of processing units or CPUs that are available for use.
4. It does not count logical processors or hyper-threaded cores; it only counts physical cores or CPU sockets.
5. nproc is part of the coreutils package on Linux systems and is typically pre-installed.
6. The tool's output is a single integer indicating the number of available processing units.
7. It is commonly utilized in shell scripts or command line operations that require knowledge of system capabilities or hardware configurations.
8. nproc can be useful for programs or scripts that need to optimize performance by distributing tasks across available CPUs.
9. By providing a quick way to determine the number of processing units, it allows for better resource management and workload distribution.
10. It is particularly handy for programs that involve parallel processing, as it helps in determining the optimal level of concurrency based on available hardware resources.
